everything shifted. I don't want to try too hard to jack up the
horizontal pipe given its age, but if I could just a bit what could I
use to suspend the galvanized from the floor joist above it? This
stuff is pretty heavy.

There are supports that fit between studs/joists and hold the pipe.

Install one on the vertical pipe. Cut off as needed below that. Couple
the old pipe to the new PVC with a Fernco rubber coupling.
