This could of been done in 5 minutes if you weren't trying to use that tubular junk (common to most on this forum, but I hate it and don't use it ever) and just used glued fittings and pipe. Then you can do whatever you need to and not rely on direct fit.
If the s. Tee is too high and you can't install a standart ptrap . I would consider a strainer with no pop up assembly( those mostly found on commercial) think it's called a grout strainer??or I would open the wall cut the pipe to drop s tee 6 inches. Then reattach
