1,5cm discrepancy - I want to treat it

A bit of context : When I was 12, i got diagnosed with a 1cm discrepancy with the right leg being shorter. As I grew up, this discrepancy became 1,5cm.
My parents brought me to a back/spine specialist at the time, that said that the deviation was too small to do anything about it.

Well this "small" deviation generated a lot of problems (cervical scoliosis, shoulder mobility problems and injury, deviated jaw that will probably need surgery). My spine remained mostly straight tho, because my main physical activity was swimming. As I grew older tho, I started weightlifting without knowing about LLD.
I am now 23, and got diagnosed with adult scoliosis 2 years ago. I have treated the issue with a lift rather successfully. However, the discrepancy is mostly from my femur, so my knees aren't even in most situations, which still causes some problems (also being unable to be barefoot is a real pain to me).

Now I am considering surgery. Is that feasible ? If so, what would be the cost?
