Can an Active Optics unit be placed in front of a corrector? Star shapes for the guide camera would be yuk, but perhaps the system would work well anyway?

I also thought about such unit in the past, but Iím concerned that it adds complexity and not sure how long the motors that constantly move the prism back and forth last.
Yes, you could place the AO higher up the imaging train. But I'm not sure whether you'd see any distortion as a result.

My AOX is about 5 years old...still works flawlessly. The SBIG version does not use motors. Electromagnetic coils are use to modulate a "floating" refractive element's position.
