Does modifying a battery grip to fit a Fuji S2Pro count. The S2 used a lithium battery for the digital functions and four AAs to power the camera. I wanted to use only AAs so I removed the raised flanges on the battery grip to allow it to mate with the bottom of the S2. I then used rechargeable batteries saving the considerable, at that time, expense of buying Lithium batteries and providing a more comfortable grip on the camera. I should have just waited and bought a D2H in the first place.
