They have given me Plan A, B, and C options. I wish I understood them all. But these guys are pretty sharp and have thought through my situation. I do know that Plan A involves creating a new end cap from billet material. As for Plan B it sounds a lot like what you described, Plan C wasn't something that I understood.

They also plan on cutting another Woodruff key in the crank and the harmonic balancer due to the supercharger.
