Yes...that would be great! Now, to make it happen...
Well, that is kind of hard to do because of balance and the weight. I would suggest two, one on either side.
Are you thinking ground based or space-based?
yes, definitely!
You could probably be clever and just collect all the photons that weren't going down the slits -- essentially a 30m guiding camera. It would certainly be economical for dedicated long-slits. Masks would be trickier, but probably worth it in terms of differential cost vs building a second telescope.
