Moving Shower Drain Vent Pipe

Hello,

I am remodeling my master bath located on the second story of my two story home and I would like to remove a small wall to expand the total length of my shower from 48 inches to 60 inches. The only problem is that my shower drain vents up through this wall so if I take it down I need to move the vent. Would it be ok to tie into the shower drain with a 90 degree wye installed at a 30 or 60 degree angle to vent over enough that I can then go completely vertical and vent into the vent stack for my other bathroom (purple in pic located on other side of the long shower wall)? is there a better way to vent my shower if I remove that wall?

The shower drain is currently 2 inch PVC and the vent is 1.5 inch PVC, the vent I would like to tie into is 2 inch PVC and is used by the sink, bathtub and toilet from the other bathroom. I am attaching pictures of my scenario to help.

Thanks

proposed vent 3 png is doable

a would simply cap off the existing vent.

and cut a tee in where you show, rolled on a 22.5 degree angle. to go over the 2'' next to it

then 90 up in the wall or that dead space. tie the re routed vent into the 2'' toilet vent
42'' above the floor.


cut the shower floor plywood out of the way,for access, then replace it when done

Thanks for the help,

a few more questions about this, on the shower drain pipe should I use a sanitary tee like what I have now or a 90 degree wye? Also do I have to tie into the vent 42" above the floor or would it be ok to tie into the vent at the bottom by replacing the 45 degree elbow with a 45 degree wye fitting?

you can use a tee, because it is just a vent
it has to be tied in above the flood level rim

a toilet is 15'' you have to be 6'' above that
so 21'' floor to center. is the minimum height for the vent
