I don't think that would be much fun for the caster. They're basically being turned into NPCs. It wouldn't suit 3rd Edition balance either.
We used the Dragonstar Science-Fiction setting for D&D 3E in a campaign that was in part influenced by the Marines of the movie Aliens.
The idea was that each player should have a stable of characters, from which we handpicked one each for any given mission. Predictable enough, most players soon gravitated to one preferred character each, using the same one for every mission.

The one I gravitated to was a pacifist android (think Bishop of said film) wizard. Loads and loads of utility magic (scrolls in internal data storage!), no offensive magic. And she was an absolute joy to play! The good experiences from that campaign has influenced how I built every spell caster since...
