That's not a bad revamp, actually. Miriam Sharpe being a Skrull . . . not sure how I feel about that, though. I can see her working as an agent provocateur of sorts to plant the seed of guilt and doubt in Tony's mind that leads him to side with the CSA, but making her a malevolent alien infiltrator feels kind of like invalidating the genuine grief and anger a lot of people in the MU were feeling after Stamford; she just happens to be the public face of it. Aside from that, Gyrich being a Skrull all along makes some sense, as it would be the perfect cover and given the actual Gyrich's usual characterization, nobody would suspect a thing was amiss about his actions or attitude. Plus, having the Cape Killers as a privatized anti-superhuman force wipes some of the moral stain off S.H.I.E.L.D. if the Cape Killers are the ones leading the charge and S.H.I.E.L.D. is just forced to play ball because they screwed up too many times, thus making it more believable for superheroes to continue working with them after the Civil War's been resolved.
