There are a lot of reasons telescopes use mirrors over lenses, only some of which this resolves. Also, will Capasso's work scale to the meters wide telescopes that you want so as to collect a lot of light?

It seems likely that any application that uses diffraction has higher-order effects that send part of the light in unwanted directions, even if there is a distinct focus.
