I would say 'No', because a normal damage attack already does Body damage, with or without Penetrating.  Does Body only allows attacks that normally deal no Body damage to do so.
 
So the question becomes, What are you trying to accomplish by adding Does Body?  If you're looking to make a Normal Damage attack do Penetrating Body instead of Penetrating Stun, that won't do.  You'll need to use a Killing Attack with Penetrating to do Penetrating Body.

9-year-old: "Dad, can we put the Ready Player One soundtrack on my iPod?"
 
Me: "Sure, let me fire up iTunes.  Oh look, it has 'We're Not Gonna Take It' on the album.  That's a good song."
 
(time elapses)
 
9-year-old: "Dad?"
 
Me: "Yes?"
 
9-year-old: "You were right.  It is a good song."
 
Me: "Good boy."

I think the first question to ask is not the dice mechanism but what role you want killing attacks to accomplish.  What is their role mechanically?
 
I think the original role was to cause BODY damage, possibly more focussed on inanimate objects like walls and robots than people, though the name does not imply this...
 
 I am not sure there is a need for an attack that kills more easily, that inflicts increased amounts of BODY damage to characters as an inherent ability, such things can be accomplished by other means.
 
Your suggestion accepts the need for a killing attack but I question even that.  Should we have a more efficient way of inflicting BODY, possibly for busting people out if jails and entangles?  Very possibly, but could that be through applying advantages or manoeuvres to existing damage? I think so.
 
I will apply myself to your question but I ask you to take a step back and ask yourself whether you actually need a killing attack at all?

Up until a few years ago, the Hero Games website hosted a wide variety of book excerpts, supplements, and game aids for free download. However, with the most recent website upgrade, most of those items were considered not resource cost-effective to maintain, and were discarded. As a result most new Hero gamers are unaware they ever existed; and even some of the veterans may have missed the treasures they contained, or have since lost something from the collection they once had.
 
However, thanks to the magnificent Internet Archive Wayback Machine, virtually all those items are still obtainable if one knows where to look and what to look for. But since many people don't know, I thought it would be helpful to provide links to representative archived pages.
 
These downloads cover many areas: maps (from published books or supplementary), book excerpts and introductions (including supplementary info about the published official settings), wallpapers, color covers to PDF books, character sheets and hex maps, items cut from books for space (including supplementary forms mentioned in various books), adventure modules, character outlines for illustrations (under "Character Sheets and Hex Maps" for some reason), illos for cardboard mini figures, apps and utilities, graphics and sounds, and more. Many of these were generously created by Hero fans.
 
Because the website has gone through several revisions over the years since DOJ bought the Champions IP, and each version has made changes to the downloads it hosted, I'm including links to Free Stuff pages from different years to cover as many of the varied offerings as possible.

NOTE: Sometimes a file linked to on one of those pages would not actually have been saved on the particular day that page was crawled by Internet Archive. At the top of each page you'll see a graphic representing how many times the page was crawled on various dates. Clicking on that to get to another date will bring up another page, on which the item you want may have been saved.
 
I recommend exploring. There's much there to enjoy.

Took our six year old to see it with us.  He honestly cried when Panther went over the falls.
 
But at the end of the movie, with Panther holding Killmonger, he asked, "Do you think he'll be sad that his friend is going away?"
 
They NAILED this movie.

Syren of the Screaming Death

When people think of "magical intelligent weapons," they always think of swords.  Always.  100% of the time.  I chalk it up to an appalling lack of imagination.  I mean, who says a quarterstaff can't be imbued with magic and become a vessel for a spiritual essence?  Well, pal, let me tell you, it can, because that's what I am.  And at least I don't have to spend most of my time with my head stuck in a scabbard.  I get to see a whole lot more of the world than your average magical sword, let me tell you.
 
But where are my manners?  Allow me to introduce myself:  I'm Beuregard, but you can call me Bo.  That guy in black carrying me is my buddy Duke Lucas.  I found Duke -- well, he says he found me, but that's just humancentric ego talking -- when he took a taekwondo class after his brother moved out of state.  He wasn't the greatest fighter, to be honest, but I could tell he was a good guy, so I let him carry me around, and in return I help him fight crime.  Believe me, giving ol' Duke the fighting skills of generations of martial artists has come in handy!
 
We're just a couple of good ol' boys, never meaning no harm... but it seems like a lot of harm comes looking for us.  First, there was that piggy mayor and his idiot police chief.  Ye gods, was I glad to be rid of them when we moved to the big city!  But now we're fighting goons in green, cultists, and what have you.  It's a busy life, but then again, what the heck am I going to do with my time?
