Full TT worth it?

I’m 39, 5’9” 147 lbs, athletic/fit body type. I’ve had a twin pregnancy (c-section) and two singleton pregnancies and am done with kids. I’m currently signed up for a mommy makeover and am sure about the BA, but having second thoughts about the TT. I have “significant” diastasis above and below the belly button, but minimal loose skin and fat. My PS (who specializes in body surgery, TT’s specifically) said I need the full TT in order to do top to bottom muscle repair, and that I will have either an inverted T scar or a floating vertical scar depending on how much my skin stretches. I’m worried I’m setting myself up for a high scar that will be impossible to hide in underwear or a bikini. But, I’m tired of sucking in my stomach 24/7 to not look pregnant and I have constant low back pain lifting weights and my kids. I’ve seen very few photos of people who have severe diastasis but minimal loose skin. Is the MR worth the scar?
