Okay, we can take as given that pitting a 30-something veteran mid-range flying brick with energy blasts against a teenage street-level size/shape-shifter still feeling her powers out is more than a bit unfair. But what would happen if some-entity switched the current powers of Carol Danvers and Kamala Khan, gave then 30 seconds to notice something has changed, and tossed them in the ring to have it out?
Would it make much difference if they were given a week (with regular Danger Room access) to adjust before the match?
