Modular Abilities and Limited Use?

[Vaevictis Asmadi]

Is there any way, without breaking the system, to create an Enhancement for Modular Abilities (Cosmic Power) that allows a character to "add" points to their Cosmic pool by buying Disadvantages? Not just any Disadvantage, but specifically those that apply constantly rather than having a periodic trigger: ie, One Arm or Blindness, but not Draining.

First I thought +100% for a Cosmic enhancement would be OK, but that seems very under-costed. If all the Disadvantages I thought would be acceptable were added up, attached to the character, and then countered by giving them enough Cosmic Power points to buy off those Disads whenever they like, then I get over 600 modular pts, not including the modular points that let you buy Advantages!
