I totally understand the desire to get your body back. I had twins and there is just a pouch of skin that is never going to move from exercise or diet. My only caution would be that you should probably wait for about 6 months after breastfeeding. In my experience, my horomones didn't really normalize until well after I gave up breastfeeding. I had water weight gain and loss, sleeplessness, and general hormonal crankiness. All things you don't want when you are facing surgery.
Also if it were me, I would wait a little until your daughter is more independent. I would expect that you will be told not to pick up over 15 lbs for at least a month - and you really can hurt yourself if you do it anyway. The 12-18 month stage includes a very large amount of holding and carrying, and some fun times you wont want to miss while you recover.
So the long in the short is I would definately do it, but I would give myself a little more time - really what's one more swimsuit season when all eyes will be on your little girl anyway.
