Body-mount 1015s should work just fine. I have True Scale Couplers on both of mine.
There are some slight gymnastics involved. You'll want to pay attention to where the mounting holes end-up. IIRC the weights carry current and are separated by a divider molded into the body, so you don't want the screw bridging the weights. I also had to carve out the divider where the screw would fall, otherwise the hole would drill off-center.
