The weight difference is negligable.

Gas tanks come in all sizes. If you are converting to pure LPG (IMO the only way to go) you can remove the existing fuel tank, and replace it with a gas canister.

Remember, I'm only playing the devils advocate here. I dont reccomend going down the LPG route in this particular case.
