[PU4, Powers] What does Cosmic power modifier actually do?

I like the "rebate" analogy for Cosmic PM. You pay the full +50% for Cosmic PM, but then you get a single 50% discount when you add one or more Cosmic enhancements to the advantage. If you never bother adding any, then you still pay the full +50%, mind you, so it makes sense to add one.

Question: it seems unclear to me, but do you get a rebate / discount on your Cosmic enhancements if you have a Cosmic tier other the top tier +50% (ie, you deduct 10% from the sum of all Cosmics if you had a Cosmic tier PM of +10%)?

Also, is it possible to make a custom PM that contains the Cosmic, +50% PM (or lower tier) but with a small additional limitation, like that it can be shut down in specific circumstances? For instance, if you wanted an Angelic PM that trumped every other kind of power like the Cosmic PM, but with -5% for "doesn't work in unholy places" (or something like that). And in this case do you get the full 50% deduction off of Cosmic enhancements, 45%, or none (this one seems unlikely).
