Let’s cross over DC with other characters not associated with DC.

Bat Lash with Bret Maverick
Jonah Hex with Bret Maverick
Cyborg and Steve Austin, the Six Million Dollar Man
Jonah Hex and Jim West (Wild, Wild West)

and some sillier ideas:

Blackhawk ( during WWII) with Hogan from Hogan’s Heroes
Deadman and Funky Phantom
