New bathroom drain layout with rear discharge

[Joe R.]

Remodeling the master bath. Discovered my house is built with 2x8 floor joists. This is a second level bathroom. Current 2x4 bathroom wall is load bearing, so I'm adding a 2x6 wall at the face of the old wall. In this wall I plan to install a rear discharge toilet, since I can't install at floor due to slope and small floor joist. Also I will have dual vanity.
This is my plan. All Advice welcome. Needs to meet upc code, i think my drawings all do. The 3 inch line will run horizontally across the new 2x6 wall. I feel the first plan is the better of the 2.

Either works. I like the second drawing better.
Are you going with an in-tall tank? Or a standard wall hung with carrier?

Thanks for the reply.... The toilet will be just a standard floor mount but with the rear discharge set up.
I guess option 2 does seem to be a better set up. With option 1, any back up I would get sewage building back up the wet vent. With option 2 I should notice drain issues before it builds up the wet vent.

Would you recommend another style toilet?
