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.
