Then we need to start identifying the base elements of the class, and deciding how to balance out the various ACFs we have already, plus any other ideas people may have, and create class feature choices.

First order of the day would be to figure out what of the class (except the hands mechanic itself) should be permanent. We also need to decide whether to make it an average BAB chassis with full BAB progression as a first level option or not. That would mean the 1st level choice would dictate if you're primarily combat or support. Other options can come off at tangents thereafter...
