You are looking for ways to make higher SPD cost less END while ignoring the fact that higher SPD is definitely better than lower.
 
Glowbug doesn't have to last as long as Aegis because in one turn he accomplishes as much as Aegis does in three. 
 
Higher SPD is a choice and I've never before in a  thread seen it discussed a making a character weaker. In situations that require less END use, the higher SPD character can lower their SPD to conserve END. Not so, if the situation is reversed, the lower SPD is just left behind and SOL.
 
Perhaps some the higher SPD builds with these problems should change the way their powers are constructed rather than changing the rules of the game to help an edge case.
 
Sorry if this seems harsh, but it's very simple. Higher SPD is better than lower. That's why it costs more. The only drawback is END use so why would you take away the one thing that somewhat balances this?

To me it's more the skillset required. 
Anyone can clean a room decently, and unless they're sloppy about it nobody but a perfectionist is going to complain. 
Anybody can try to destroy evidence, but the cops are a heck of a lot better at finding evidence than John Q Notamastercriminal is at getting rid of it.  A fast mundane cleaning is still as likely to leave evidence as a mundane-speed mundane cleaning. 

For what it's worth, 
 
be mindful of the little reaction face that looks like sympathetic sadness.  It's actually just "you made me sad" and inflicts negative rep just like the down arrow does.  Don't use it unless you mean it.
