I’m not a doctor but I imagine the old school c-section would be a big no for your provider unless it is medically necessary; they have research based reasons they have come to prefer the bikini line incision (healing time I believe being a big one). As far as scar tissue, I think that will depend on your body- did you have excess scar tissue with your surgeries? If not, I would not stress about excess scar tissue with this surgery.
I know there are several ladies on here who could tell you about vaginal delivery option and had great experiences going that route. I personally chose to go c-section despite two healthy vaginal births prior to my pouch but that was just my comfort level.
my c-section scar is very thin compared to my (traditional cut) colon removal scars and so low down it is never seen even in a bikini.
