Any chance you could help with that?

I'd say utilize the big match ups of the Marvel VS DC storyline from 1996. These include -

1) Captain Marvel/Shazam VS The Mighty Thor
2) Sub-Mariner VS Aquaman
3) Quicksilver VS Flash (Wally West)
4) Jubilee VS Robin (Tim Drake)
5) Silver Surfer VS Green Lantern (Kyle Rayner)
6) Lobo VS Wolverine
7) Catwoman (Selina Kyle) VS Elektra
8) Storm VS Wonder Woman
9) The Superboy Clone VS the Spider-Man Clone (Ben Reilly)
10) Superman VS Hulk
11) Batman VS Captain America

Does that help?
