Theoretically, the dashboard stuff (damper motors, etc.) should hold their positions indefinitely unless you're always moving the air distribution switch. On our '89, I can park the car overnight, & there's still a good vacuum in the canister. Because in the morning I can move the air distribution control without starting the engine, and the dampers will move.
If yours doesn't hold vacuum overnite, or at least a few hours, then something is leaking. It's probably cheaper & easier to find & fix the leak, rather than invent a system with a vacuum pump. Its a neat idea, but I bet the check valve on the vacuum canister is leaky.
When everything is quiet, turn off the engine & listen for the hissing noise of a vacuum leak under the dashboard or at the vacuum canister.
