Your thinking about smaller lighter components is sound. It's not too hard at all to de fork a CPC925, but it's generally considered a one way trip. You'll only need basic tools ... a good set of imperial allen wrenches (the one for the plastic covers is not a popular size) and a large Phillips head screw driver, and a bit of care. You have to loosen one of the fork arms from the base a little bit so you can spread the fork arms as you remove the ota. A blanket and an extra pair of hands are usually a good ideas too.
Then buy a good Losmandy D type plate and radius blocks for the C925 (Losmandy or ADM) and mount it on your favourite gem. Remember that the Atlas/EQ-6 mounts have a smaller Vixen compatible saddle (can be upgraded ... see ADM) and while Celestron does sell a C925 with this smaller mounting dovetail bar it's not generally considered a great setup ... the wider and more robust Losmandy D type plate is preferred with the C925 ota.
One other thing to consider ... you'll never really get a good price for the forks/base so unless your CPC has exceptional optics I would consider selling it complete and buying a C925 ota.

If you sell it all and buy just an OTA you may do better. Unless as he said the optics in that tube are something extra special (which is possible).
I can be done, but if you go back and don't do it correctly you or someone you sell it to later will have a devil of a time with pointing accuracy... FWIW... Joe
