It seems that you need to prepare your future surgeries very well. First, a general medical clearance with medical history, exam, and labs.
Second a coordination between the different physicians taking care of you is essential. A smart lipo first followed later on by a fat transfer could be counter productive, as you will need this fat in the future for the transfer.
It is not uncommon to allow 3-6 months between surgeries if you are healthy to allow proper recovery.
Best of luck!
