It would be neat to aerate it without breaking the closed system. Maybe a magnetic connection through the glass. Motor on the outside and prop on the inside... Does add complexity though.

Probably almost every wet-bench lab has a magnetic stir bar, as in [0].

But that would just mix in air from the top of the jar?

Oh I guess I don't understand what it means "to aerate" then.

If you're not changing the air, then it will already equalize very quickly without your help.
