Tub Drain Question - Want to move

Ok here is my situation and what I am wanting to accomplish.

Currently my tub drain setup looks like this underneath:

The problem is the water trap area is so low its going to knock my drop ceiling down to an unusable height. What I want to do is turn the whole thing 90 degrees (clockwise in this picture) and bring it up higher into the cavity. Then it will elbow back right after that. Is that ok?

Here is a diagram of what I want to do.

Again, the reason is simply headroom. My basement is only 8 feet tall to the top. Even with the pipe itself down its bringing it to a bit below 7. If I leave this as it is it brings it to about 6'4. Way too short for me at 6'6. Also boxing just this in seperately will not work as this is right in the doorway.

can you swing it to wall on left and box it in, as long as you can maintain proper fall

Your diagram looks OK as long you DO NOT have any level drain lines or any back pitch (water running back towards the trap). You must maintain 1/4" pitch per foot running away from your trap towards your main sewer.

Thanks guys. The pitch will actually increase a little bit. Is that ok? Meaning it will be a bit more 1/4.

Stay between 1/8" and 1/4" per foot slope and make a vertical drop to make up any difference. Also be sure to use sweeping ell's or two 45s for any turns. The problem with to much slope is the water runs away faster than solid waste can be carried away. Anything over 45 degrees or 6" per foot is considered a vertical drop.
