Eliminate charcoal canister + stuff

Without getting into the argument of whether you SHOULD remove the canister, the correct way to do it would be to install a vented filler tube from a 70 and down A body. then you could block off the second line at the tank (or even install a pre 72 unvented tank) and just run with the system that worked from the 60's to the 70's. I'm looking at the same issue on MY 72 right now. The tank is leaking badly and I have a good 68 tank in the shop.
