I’m not 100% sure but I think there are some fundamental differences between wide-body and narrow-body aircraft (things aren’t just a different size but different shapes) that mean you couldn’t just shrink it down and change the seat pattern, but I expect they definitely could base a new aircraft on the same materials tech, avionics, etc. as the 787.
