   Only if you could hold the distance between them stable to within a   
   fraction of a wavelength of light, *and* beam the light gathered by one   
   to another across that distance without losing much of it.  That...   
   presents problems, to put it mildly.   
      
   People are still struggling to make imaging interferometry work well at   
   distances of a hundred *meters* with both telescopes resting on solid rock.
