Asteroids are always "rock", but turn into any of Ice/Gas/Rock when planetized.

I believe that if you keep smashing and rebuilding, you can get any atmosphere with any surface. Thusly, with enough time and budget, you could colonize all planets in a "own atmosphere/surface only" game.

These are always subject to the restrictions of: no Gas/None, Gas giants are always large or huge.
