I encourage your pursuit and heartily endorse spending your money on a big SDM with Argo Navis, Servo-cat and the other bells and whistles...
As was noted earlier, I think that Rumples Riot is doing some work imaging along the lines that you are thinking about.
While I am not an imager at all, I think that the visual performance of a big SDM that tracks would be glorious even if you could not take a picture with it!...but I think you can enjoy both with the right set up...I just don't know what that is...
Cheers!
