It shouldn't be a problem. There are many encounters outside in the desert, and most of the major opponents are inside large rooms with very high ceilings.
I like to create a character based around a miniature. I've created some pretty interesting ones, such as a slutty oracle of Pharasma/summoner who's eidolon looks like a giant scyth wielding grim reaper-like psychopomp (Anima Tactics miniatures)
