Can my tummy tuck scar be lowered? (Photos)

Hello doctors, I am interested in lowering my tummy tuck scar. I'm aware that I may not be able to have it lowered much, but I would at least like for the scar to be straight. The original surgeon extended the scar too much and I ended up with 'dog ears'. The scar is not straight and it bothers me. Do you think the markings for my desired scar are realistic? Any information helps.
