I think the corrupted gems are more likely enemies. The Crystal Gems don't seem to exhibit any familiarity or kinship with the gems they bubble (and the only one we've seen come back, Lapis, neither knew them or cared about the Earth), and them being former enemy forces would explain why GAP looked so disturbed when Steven said the mirror was "like a person".
