Tough one!
Phantom Lady = Black Cat (Harvey), Lady Luck (Quality) or Senorita Rio (Fiction House)
Uncle Sam = Puppeteer (Fox), V-Man (Fox), Captain Freedom (Harvey) or Man of War (Centaur)
Black Condor = War Eagle (Lev Gleason), Green Lama (Hillman), Stardust (Fox)
Human Bomb = The Comet (MLJ) or Microface (Hillman) or TNT Todd (Centaur)
Ray = Wonderman (Fox), Atomic Thunderbolt (Regor) or Nightmare (Hillman)
Doll Man = I'm stuck here. Mighty Man or Minimidget? (Centaur)
I know I'll think of some I forgot later. And yes some don't make sense but they have a cool costume and isn't that half the fun of sticking various heroes together for a commission?
I hope that helps.
