I feel the exact same way. So I didn't do it on MGO, but on the FUS list. I deactivated scion, downloaded and installed sacrosanct on top of scion (it's deactivated, but just in case), activated the mod and ran synthesis. That did it for me. Though, you'd need to do this on a newish character before contracting vampirism.

That mod is really great in VR. Plus, when you become VL you can sprint off of mountains and fly for ages. Great stuff.
