Recently I modified my B-Wing to allow for the depicted rotating cabin, for that first I broke the peg plug on the engines and drilled a hole to fit 1 magnet, decision I regretted almost instantly, as the magnets worked but not all the time so I drilled a side hole to remove the ship side magnet, and after that I drilled a bigger hole one where 4 magnets went in to the hole, 2 were left inside the ship and one was glued to the peg plug so it gives stability to the union, that did the trick to have a stable ship. As for the cabin I forced the window part out and it slides out of a big peg inside (just like the ship stands but bigger), I only sanded the hole on that part to allow it to rotate and removed a portion of the peg to accommodate 1 magnet one on the ship body and other on the cabin, with that the ship rotates as shown on the movie, hope you like it.
