Marvel's LotR

I'm doing a franchise masher. I just watched Fellowship of the Ring and came up with a few
 
Beta Ray Bill the Pony 
Gandalf the Strange: Sorcerer Supreme 
Aralogan's bones are forged from pure Adamithril

I can't tell if this is a really bad idea or one of the best ideas ever. It's sounds convoluted and insane, but also crazy awesome and cool.  I'm stumped here. 
 
Good luck with whatever this is, hopefully it comes out awesome.

That would be interesting lol, I'd like to see that or DC vs. LOTR lol something

Jarvis Gamgee: Servant and Gardener 
Legolas Barton the Hawkeyed Elf
