I think you're really smart to avoid excess surgeries. If someone makes a mistake in there, it might not be a solvable one.
The idea of doing embryo-banking is interesting, though. I'm sure it would be super-expensive, but that might be a way to sort of go nuts with stockpiling the embryos, as the PP said, and then treat the endo (either with BCPs or lap or both).
I'm thinking of you, sending you all my best wishes, while you figure this out.
