There's always a way, it depends on how much money you are willing to spend to convince someone to do it. Penile inversion already uses the scrotal tissue to a substantial degree if not completely, so there would have to be additional skin grafts taken from somewhere. Just watch one of the GRS youtube vids or animations and you can see where the tissues are reassigned.
I'm not passing any judgment on you here, but given the WPATH standards of care that most GRS surgeons require, you may find getting the appropriate documentation a bigger challenge.
