You're asking for too much . .a soft pad at that. By the time you get all that done it might be in worse shape that before. Slap some wood on it, tape it to the floor or buy a Metal pad simple as that. . AND next time you might not get help because the OFFICIAL SOFT PAD DISCUSSION isn't made to be ignored. . .people DO answer questions.
