Robert Downey Jr; Jensen as Iron Man

[flashbacklife.livejournal.com]

I was watching the Iron Man movies this morning, and I was struck with how very funny it would be to see Jensen cast as a Tony Stark character in a story. 

Alternately, I have read one story out there where Jensen is Capt America (that he was not is Hollywood's biggest mistake today - well, that and maybe the entire second Transformers movie...).  I can't recall it right now (I'll post the link if I can remember it), but let's face it, RDJ is a character all to himself, in the flesh or on camera with a script.

So I'm curious: are there any stories in which Jensen has been cast as a playboy/superhero ala Tony Stark, and are there any other stories with J2 that have RDJ as a major character?

Gen or slash good.

Thanks
