Why not throw in some Wanted characters like Wesly Gibson, Mr.Rictus and his followers, and maybe also here are some ideas.

S@!thead (Wanted) vs Clayface

Sebastian Shaw vs Red Skull

Black Mask vs Hammerhead

Reaper (Paul Gruener) vs Brutale (Guillermo Barrera)

Scarebeast vs Charaxis

Onomatopoeia vs Tally Man (The first one)

Zebra Man vs Polka Dot Man

The Eraser vs Condiment King (Just a funny idead I had)

Orca vs Ratcatcher

These are just some ideas I had. Let me know what you like and don't.
