Toilet flange to main line 18" drop and 15" run can it be done???


Is it possible to install a closet flange 15" o.c. away and 18" o.c. above the main drain line? Even with all things being perfect and no obstructions? Currently there is a 6" Duct in the "straight" perpendicular to pipe location but the tie in must be a Wye anyway. Not being 15" drop keeps it from being a 45 degree angle. Simple rise/run is distance about 23" and 50 degrees. Should I look to put toilet somewhere else?

After thinking about it can I install a tee immediately after the Wye connection and place a vent so it vent is not in the 23" section? Also the main soil stack vent is 3' downstream from the new tie in, So total run of 5'. Shouldn't that be legal or does 100-110 degree turn force it closer?

Sketch is bad but like this: All the lines to the right will be cut and capped. New shower will be connected to the new Wye on left. Other pipe is laundry drain no longer a laundry. The 3" to far right is toilet that is being moved to this location.

Upstream is hall bathroom and kitchen drains. Hall toilet currently has no vent but will have one added. Kitchen and hall lavatory is already vented.

If code allows the toilet to be 15" o.c. I can theoretically move the toilet 3" to the left which would make it a 45 degree angle but I still would need to maneuver around the duct. I am more concerned about the connection to properly vent it than anything.
