I wouldn't think LEGO would do this because this would mean a lot of new molds on top of what they're doing already, and this also would mean more licencing rights, the company might get into financial trouble again like they did a few years back.
Actually you see one quite a lot in Episode 1, his name is OOM-9, he's in the start and battle sequence in the plains.
You also see quite a few others throughout the movie.
Hope this helps! X-D
I bought three, but only built one 8-| ... I'm using the Bley in my layout. I also made a cool little ballista thing by removing the catapult and adding the crossbow attack cart without wheels to a 6x2 flat frown plate on the turntable thingy.
Shooting down Dragons on! :-P X-D
The only problem I have with red and black is the continuation of Vladek's Scorpion Knights :-| , but maybe Barbarians wouldn't work... I mean we already have Trolls :-P .
Maybe a Forestmen faction? and we could have some smaller Goblins for the Orcs. I mean, that's sort of expanding on the factions already there. X-D
