For your first thought - if we could capture the phase information of the incoming light, then yes. We actually already do this for radio waves- you may have heard of synthetic aperature radar, or AESA/PESA radars in a military context, or the event horizon telescope network (the thing that got us the 'first picture of a blackhole').
For your second thought - as literally described, such a thing would probably be badly impacted by solar wind.
