Better Buddypress Intergration

Im using the Membership plugin and im wondering is there anyway to better intergrate it with buddypress

im dont really need its account page or the subscribtions page, ive set it up with fb plugin so people can auto register and fb fills in the buddypress info, all im using the membership plugin for is so i can reserve certain pages, permissions and widgets etc for premium members, so i want to add a option on buddypress profile for the user to be able to upgrade to premium for a 1 time payment

how would i go about this?
