Yes you can. But power class should be same in both: original and donor.
Change vin from cas replacement-> advanced.
From FA manager backup original FA and restore it donor.
Copy isn from original to donor
Copy keys from original to donor (key learning->option 1).
Restart session(leave BMW software and return back)
Encode donor cas, then it is done.

Check from manual coding: cas power class, dme power class must match.
Copy FA from frm
Read isn from DME, right to donor CAS
You will loose original keys
