Well, technically anything is possible, so while this would be possible, it would be a son-of-a-bitch to do, I'm sure.
You'd need the blend box, all the cables, the control unit, and likely many, many other pieces from behind the dash on a manual HVAC equipped model. I'm not exactly sure of what all you'd need, but if you're dead serious about it, the way to go about it IMHO would be to buy a totaled base-model Wrangler from CoPart and then you'd have the donor vehicle, which always makes swaps like this much, much easier.
