Saw a Wuxia film festival a few years back and it all could be adapted pretty easily. Lighting candles at 20', running up trees, snatching ghosts from mid-'air'. Flying carpets, straight up spell slinging and amazingly choreographed stunts. Wouldn't take much more than putting in a few powers here and there. More often for monks and sorcerers, and less often for the honor warriors and sneaks and hardly at all for the tramps and scoundrels.
Prestidigitation, jump and climb speeds, forced manifestaton ethereal grappling. Clever magic items, imaginative character concepts and DMs and players willing to get into it. Switching out class abilities or simply adding them early and often should be easy enough.
The DnD mechanics that funnel these things into a die roll that determines success or failure and not a free flowing action extravaganza would get in the way. Encouraging a 'take 10' on these things when possible would help create the cinematic flair necessary to the spirit of it.
As long as it's fun, who cares where it's from.
