Wheel spacing/compatibility is a bit of a hit/miss kind of thing, but you have a good chance of it working. We dropped a 9speed/cassette wheel and hub into the backend of my son's 86 Fugi 12 speed. Just a slight spread on the frame (by hand) and it works perfectly in friction mode. New Chain was in order. You are updating from 27" wheels? That may cause a few more issues....or not.
