This wont be pretty.
...stop right now, take a break, have some coffee, and relax. Then whenever you restart, apply some 50/50 acetone/ATF mix penetrant to the drive side threading, give it 15 minutes to wick in, reapply and attatch your cup removal tool firmly to that side using a bolt threaded the same as a crank bolt, but long enough to reach out past the removal tool, with a fender washer outside of that tool so you can firm it up.
Use a Crescent or other wrench on the tool, and strike it firmly a couple of times with a dead blow or other hammer to break any corrosive bond in the threading with impact. Once you have the drive side and the BB sealed unit out, you'll have better access to the plastic cup you're having trouble with, and maybe you can just cut it in a couple of spots and break it out from there.
