Question:
Can we program the Itron ACE6000's profile for kWh instead of Wh?

Answer:
When accessing the profile, the ACE6000 returns the energy values as unsigned16 bit integer values (range: 0-65535). It sometimes seems to change to int32 instead of int16
The way it looks like at the moment, is that we will do well to stick with Wh, and meters with no CT or VT programmed into them, since our range is rather restricted.
