I'm not sure I understand what you're asking, but yes, you should be
able to set up any class that derives from Controller this way.

Yes, by creating a Controller instance that does your bidding. It's
often useful to have a function that gets called on every frame, such as
control_dynamic() in the visual_jitter.py demo.
