How tricky would it be to retrofit the dual zone climate control in place of the manual controls?

From the microfiche it looks like the only additions are some control servos, a deletion from the body control module, and an addition to the PCM.

Would it need to be reprogrammed? I estimate it would cost about $1000 to do so with all new parts, but there are a few yards in my area that have them, perhaps I could get a deal for buying a large chunk of the HVAC system.
