If I had use of DCv1 and all of its tasty polearm and monk feats, I'd build some kind of monk who 1) used a polearm as his main monk weapon (Feat: Pole Fighter) or 2) used a standard martial weapon as his main monk weapon (Feat: Unorthodox Flurry) or 3) could do that nifty cinematic martial-arts unarmed striking from a distance thing (Feat: Ring the Golden Bell)- all have prereqs but have high cool factors.
I'd also probably start the character off as a Psychic Warrior, to add a couple more feats & the Expansion Psionic power.
