Swapping flushometer toilet for conventional toilet

[BLS33]

My house came with a flushometer setup that I want to get rid of (for resale aesthetics mainly). The rough-in for the toilet was 8 inches, so I took the wall back a bit to make room for the new toilet, now how should I go about getting the supply line connection I need? Right now it has a tee that leads straight to the flush valve. I need to get the tee out of the way because it sticks out taking room away needed for the tank. So should I turn the tee so it is out of the way and cap it? Then do I need to cut into the pipe to hook up the supply line to the tank? Here is a pic that may help you understand what I'm talking about:

Normally, that valve is used for commercial applications only. Remove it completely and reroute the incoming water thru a reducer into 1/2" pipe, and have it come out of the wall at about 12" above floor level. If I remember correctly, the floor toilet flange should be set 12" away from the wall for a correct fit.

If I am seeing correctly, the piping is galvanized. If you just turn the T sideways into the wall, you will almost certainly cause a leak on the side of the T that will be loosened up. This is not something that I would try to coach someone through via the internet.

Why not keep it? You'll have good wOOsh for those big dumps.

Nailer hit the nail on the head. My dream is to have a Sloan Valve Urinal. There is nothing like that woosh!
