Developing against a beta API for an unreleased platform is going to be outrageously frustrating on a brand new MacBook, I can't imagine how infuriating it would be trying to do the same on a Hackintosh.
If your goal is to hack around and try to get anything at all to work it might be fun, if your goal is to actually build a working VisionOS app, I'd probably suck it up and spend the $1000 on used MacBook.
