rear end questions

[i heart square bodys]

okay so i want to put a 12 bolt in my truck. i realize that it is easier to find them with 6 lug pattern but id like to keep the 5 lug. i have a pile of 10 bolt rear ends with 5x5 lug pattern and was wondering if the axles will interchange. also wondering if the brakes will do the same ? now my other thought was to maybe get a 12 bolt with disk brakes but once again the problem arises that i want to keep it 5x5, any way i can do this without having to drill out the rotors (any other oem rotor from other aplication) if i can get the prefered axles in it. thanks !
