Maybe after replacing clutch and belt, if that's all needed to run system, it will work even if only a little, then I would know it's ok to convert to whatever....I guess. All I know, is that I took it to a locally recommended repair facility and they wanted like, $900 to overhaul, replace compressor, fix etc., w/o even so much as touching any part of my system, so I want to avoid "the pros" unless absolutely necessary. Of course I may need them to vac/flush system, but other than that, I can and want to do it. I've read so much about being able to do so, and I've done harder jobs on past auto's.
