With 2 surgeries very possible. With one impossible.
Man I think doing this twice is going down a big rabbit hole. Asking for athletic abilities is like animals in the slaughterhouse asking for freedom. Stupid comparison but look, it takes long to recover from the first surgery then another long while until you do the second one, then the same stuff again. Eventually you may recover fully after maybe 5 years but I would fully get athletism out of your head. If you care about that don’t ever do this surgery, not even the first one. If I cared much about me climbing again asap I would be extremely miserable. I made peace with myself knowing I may never do it again.
Proportions with 2 surgeries is no problem, only potentially a problem if you do a large amount on one segment.
