That is effectively what I did with my C925. I deforked it about 5 years ago when I was using purely for visual and put it on the Orion version of the AZEQ6. Since then I have added the 0.63 reducer and a luminance filter (To combat reflections) and I have been using it for AP for about a year. I am sure an Edge HD would be better, but I would have to go to an 8" to be able to afford it. If I was sure the Edge 8 would be a step forward I would put the C925 back on the CPC mount and sell it as a visual scope and move to the Edge HD.
Regards automated focusers, I would go with the ZWO now that they have a mounting bracket for the C8-C9. Unless they have added one to later versions, the Celestron motor lacks a temperature sensor. The C925 changes focus rapidly enough with temperature changes that I have it do a focus run every half an hour all night and the time to do that adds up, that could be spaced out significantly if there was temperature information to work with.
The Edge HD 925 on CGX mount is about $500 over your max budget, though then there would be a reducer to consider.
