Or just orient them sideways to block less light. That shouldn't cost much fuel, if any (using reaction wheels). I think it would be best to keep those at hand,

Or just orient them sideways to block less light. That shouldn't cost much fuel, if any (using reaction wheels). I think it would be best to keep those at hand, just in case. If feasible at all, make a part of those shades photovoltaic panels, and beam the energy back using microwaves, as that would provide an extra incentive to launch that (GEO might be more useful for that kind of setup, I have no idea what deltav it would take to transfer to/from both, but you could use ion thrusters since you have on-board power).

How do you orient them? The dumb ones weigh 1g. How much will they weigh if they're smart, powered, and have reaction wheels for orientation? That's orders of magnitude again. Better to send up 10,000X dumb shades with random orientation and spin. Not only are the dumb ones much lighter, they're proportionally much cheaper too, since they're basically just structured aluminum foil rather than needing thrusters, reaction wheels, computers, etc.
