Can't believe I've never tried this one yet, given they're one of my favorite unsung Marvel teams. With that in mind, I give you the DC Comics version of
The Rangers!

1. Red Tornado for Texas Twister (both have wind/tornado-based powers)
2. Vigilante (Patricia Trayce) for Shooting Star (both blonde gun-wielders)
3. Black Condor for Red Wolf (both Native American heroes with ties to animal symbology/abilities)
4. Fire for Firebird (both flame-based women of Latin descent)
5. Lightning for Living Lightning (both have lightning-based powers)
6. Black Pirate for Phantom Rider (both spectral versions of heroes from past eras; Black Pirate here is the ghost version we saw in Starman)
7. Starman (Mikaal Tomas) for Fifty-One (both aliens with sizeable powers that haven't been fully explored yet)
8. Congorilla for Armadillo (both giant orange animal monster types)
