As discussed in an earlier post, I'm re-modelling our main bathroom.

I'm not a pro, so it's quite a challenging project for me. The original shower stall, sunken bathtub and toilet were installed on a raised tiered structure and the wife wants it all on the same level, bless her. I've managed to sort out the drainage for the new shower stall and stand-alone bathtub, but would appreciate some advice on the best toilet drain (3" pipe) configuration.
The toilet was originally raised 7" above floor level and when I dismantled the platform I found that the lead sleeve was set too high to be usable; it was glued into a 45 degree elbow connected to the side arm of the wye hub tilted up 45 degrees. I didn't take a photo with the lead attached, but this was after I cut the 45 degree elbow off.
I can’t drop the Wye piece any lower without compromising the run off slope to the main drain stack. So I’m weighing up the available options. For now I’ve removed the Wye hub section and replaced it with a length of pipe so that condensate from the vent stack can drain.
If I fit a Wye laid flat with a 90 degree elbow that would give sufficient depth for a new lead sleeve but it would set the flange centre point too far out (14") from the wall (allowing for drywall and tile) and the toilet has a 12” RI.
A possible work-around could be fitting two 22.5 degree elbows on both sides of the Wye hub creating a 'chicane' that would bring the flange closer to the wall. Here are the pieces laid loose to show what I mean.
My concern there is whether the ‘kink’ would be more prone to blockage, especially if crap got backed up into the short section between the wye and vent. And also whether code allows for this ?
The only other option, I can see, is going back to the original configuration (a 45 deg elbow off the Wye) and fitting ABS flange instead of a lead sleeve. I’m going to be applying Ditra XL on the 3/4” OSB and tiling (3/8” tile) over that. That should give just enough floor depth (around 1-3/4’) for an ABS flange inserted directly into the 45 deg elbow.
Although the cheaper option, I am concerned that an ABS flange would be less robust (more prone to cracking) than a lead sleeve with brass flange.
