I don't mistransform the 2nd Year Decepticon jets and I know of other collectors who don't either. I generally avoid deliberately mistransforming toys, at least when they're on display. One exception would be Apeface. Because the back kibble on mine has become so loose I deliberately swing the ape mode legs all the way down towards the back. I also angle the ape arms towards the front of the robot and then clip the ape arms and legs together to hold them in position. I also flip out the ape feet 180° to help get a firmer grip. But yeah, such mistransformations are done out of necessity. Sometimes I might shift a part in to save space.
