8. I think replacing tile on an unstable subfloor

will lead to the same problems you had: breaking tiles covering up a water damaged subfloor.

Epoxy sealer won't make the sub floor stable and it gets brittle with age and will fail as the tile does.

I think you're going to want to get rid of whatever is sitting on the joists (plywood, probably; Aspenite if it was cheaply built) and install either cement board or particle board, both a lot more stable. Cement board is preferable. Or install it on top of the subfloor if there's enough clearance under the door for that plus tile.
