You left out one step/criteria:

- constrain joints so that they can be cut with a tool on a CNC with the material secured on the machine in a convenient fashion in a reasonable period of time

which is something I've been working on.

Could one make that a part of the evaluator/fitness function?

Yes, but it needs to be included as a consideration up-front and not left to afterthought or accident.
