Some time ago I tried dpb/proot for the same purpose, maybe too much as you are
going to rebuild all depends, see
https://dataswamp.org/~solene/2021-05-30-openbsd-dpb.html (easy peasy).

Perhaps its possible to pre-fetch packages and rebuild only what you need.
Please let me know if something smarter exists.
