I'd take a Chewie in a heartbeat, but honestly a whole line of it just doesn't appeal to me.
The lack of appeal is that it doesn't translate to stories I had an interest in. The Chewie I could BS as any generic alien or whatnot. I like the McQuarrie Stormie too, as I can surely use it in some capacity in my Imperial ranks.
The others just don't overly appeal to me much though, sad to say. Eh, maybe Vader... I mean, it is his story.
The EU I'd much rather have is the EU I like... Video games, Zahn's trilogy, some of the Rogue Squad stuff, and maybe a few NJO era Jedi (Not those crappy Vong though, please... Leave species 7833290210 to Star Trek).
Seriously though, that Chewie would rock talking to the Nazi Gestapo agent I have in my Cantina, and a dinged up Blue Snaggletooth I have there too... And Curious George's figure in there... And that one-eyed thing from Monster's Inc... And the 2 XD WW2 pilots in there... And the George Lucas figure I have tending bar with Wuher...
OK, the point is I could put that Chewie in there and he'd look as normal as anyone.
