A single moveable pulley would probably work, though it would need a heavy counterweight (greater than 1 kg, even without accounting for inefficiency). It could be anchored to the high IMA pulley system (one of them triggering the other).

Wouldn't that still have an IMA of 1?

No, half the force comes from the free rope, the other half from the anchored rope. Example

I know very little about physics but all of the diagrams that look like that online say that the same set up has a IMA of 2

Agreed, this would be much easier. An illustration, for those not familiar with pulleys:

Wow thanks for the illustration! Could you explain how you apply the effort in the example of the pulley system with the IMA of 0.50? Would the effort be pulled up?

Try your HS physics department.
