Byte code isn't guaranteed to be backwards compatible, so if you load byte code
generated by Emacs 28 into Emacs 26, you're bound to get errors.

Forward compatibility is much better, AFAIK, so you should be able to get
things working if you compile your packages with Emacs 26. If it were me,
however, I would give each Emacs its own space. If Elpa packages are the only
problem, you probably only need to set `package-user-dir` depending on the major
version, something you can do in your init file.
