  2. Yes you can, but you will run into precision and stability problems. I remember going to a talk by a visiting lecturer, not long after the Hubble Space Telescope went up. If you remember, there was a mistake in the grinding of the mirror, which meant that the pictures were of lower resolution than originally expected. This guy explained how they came up with a mathematical model of the lens imperfection, and developed an inverse transformation to improve the quality of the images. They were achieving some quite respectable results. A later Shuttle mission took out one of the modules and replaced it with COSTAR, which fixed the optics to compensate for the mirror problem.
