Yes, I (of course
) think it is a great Idea and really, I think any of those combinations could work
I would mount the scopes on top of each other myself with solid hard connections spaced as wide as possible along the respective OTA's to minimise diff flex with the guiding.
If the FOV's don't match perfectly it doesn't matter, co registering the resulting finished RGB to the high res Lum and doing an LRGB combine will work perfectly, I do it all the time.
Awesome approach and I will look on with much interest should you go dwn this route.
Have a nice holiday...you communist, TEC loving, mexican gunslinger...
