Extended tummy tuck, will it be enough? Or do I require a 360 tummy tuck? (Photo)`

Hi! In July of this year I scheduled an extended tummy tuck to be performed in January, but as I get closer to my goal weight, I am starting to get nervous I will require more. Should I switch providers for a 360 tummy tuck? My provider only offers mini, standard and extended. So far I am down 87 lbs, and I still have 30ish Ibs to go! I've had 2 kids and fluctuated weight gains and losses significantly. I'm scheduled for a breast lift, flank lipo and extended tuck. My backside is concerning too.
