Your wording is ambiguous enough to make this quite difficult, sorry.

There's no "return instruction" on the stack. There's just a return
address pushed on it. Of course, you're free to manipulate it in any
way, so the reti instruction will jump to something else than what has
been interrupted. That's a common method for an operating system to
implement scheduling. The location of the return address on the stack
can easily be computed.

Yes, i think you can do it that way.
