You need to either open up the wall in that bathroom or on the other side and rough the sanitary line in at the proper height. Don’t fuck around and try to reinvent the wheel when it comes to plumbing, it never works. This shit was figured out long before we got on earth by far more intelligent people than we will ever be
If is is not carrying solids i agree but the problem would be going beyond the acceptable tollerances of the mechanical joints and glue joints of the fittings.
I have seen too many times something that is forced cause major damage. The cabinetry looks nice and rather than take the time while it is not at the point of no return to make it correct would be foolish. Sometimes you need to drop back and punt 🤷♂️
