This is tricky... modifying the mount to be always 'A', (then you leave your lens at fully closed F stop), and drill contacts appropriately to set the correct aperture range could be done pretty easily. However, the non-linearity of the aperture lever is the real problem here. I can't think of an easy way to fix that... I wouldn't pay for it, but then, the M lenses I have aren't particularly expensive or exciting (M28/2.8, M50/1.7, M135/3.5, M200/4 and a crappy third party 28-80 zoom).
