, inventive setup i must admit. i once had a similar idea but eventually it ended as a blueprint only.

if i may suggest something - i would make a platform that fits the size of the trashbin entrance at the top. i would attach long sticks or metal/plastic tubes to it and connect them at the top to make smthg like a cage. i would then be able to lift the cage with the platform attached in the bottom and take it in/out of the bin.
and on the platform would sit the pot(s).
hope this is comprehensive
but i am pretty high atm so not sure i made myself clear? if you wish i can make a simple drawing.
peace and good luck
