Multiple primary reflector

I have seen large observatory telescopes with multiple primary mirrors. Could this be done on a smaller scale with long focal length mirrors? Has anyone tried this? Any ideas, alignment and collimation and secondary size come to mind.

I believe all of the multiple or segmented mirror telescopes employ control systems that continually adjust the mirror positions using computers and piezoelectric crystals. The problem is that the frames holding the mirrors are nowhere near stiff enough to keep them positioned within a fraction of a wavelength. My impression is that this would be a real nightmare to implement on an amateur sized telescope, but with a large enough capital investment and all the recent advances in optics and computers, maybe Meade or Celestron will take up the challenge.
