I've been wondering if something sitting on top of the beans in the hopper (eg a bag of rice) would stop new oxygen reaching the beans as their level drops. Ideally, the hopper would be cylindrical and the object a simple disk, but mine is the usual conical shape. Or am I over-thinking this?

That's the principle I had in mind. Applying that to the hopper is the poor man's version and there is no need for further interaction with the beans until you have to refill the hopper. When you open your canister fresh air gets in but I suppose pushing it out seconds later minimises exposure to oxygen. Using a bag and rolling the top before you seal it should achieve the same thing at zero additional cost.
