More than Two Weapon combo

[AnotherSkip]

Okies steve here is the question :
I have a race (Dralasites) who can have multible limbs (something on the order of 8+/-) Now then If I wanted to expand the Two weapon combo to make the sweep bigger should I charge 5 points per additional attack at no penalties or something different?

this is for both fantasy and Sci Fi.
I'm looking for generic "in the rules" balance not campaign specific, TWC does not seem to have a real pricing breakdown so I'm guessing here.

As noted in the Rules FAQ, "The cost for TWF is calculated based on CSLs to counteract the Sweep penalty, and Ambidexterity to counter the standard Off-Hand Penalty." Since you've already got the Ambidexterity in place, you could add more CSLs to the cost to counteract more Sweep/RF penalties -- two Levels per additional attack you want to allow.
