Moving Toilet, but soil stack is solvent welded

I want to move the toilet in my first floor bathroom and having stripped everything out, I have found out that the soil stack is solvent welded, so I cannot just spin the soil pipe around 180 degrees. What is the best way of replacing it with a push fit?

Will I need to expose and cut out the solvent welded soil pipe from the ground floor and replace it with a new soil pipe with a push fit boss pipe, branch pipe, and AAV in the bathroom? If so, can I just cut it using a multitool and solvent weld a collar and then the fit the new push fit stack?

Also is the existing AAV too low, as it is lower than the sink?
