Look up the "Deltoid Pumpkinseed" the original attempt at a multi lobed lifting airship. All blimps derrive some lift off the shape of the bag. Making them wider just increases the amount of lift. So you can take a ship that is neutrally boyant load on 1-4 tanks then accelerated down the runway and fly the heavier load. When you drop the load you just "float" back empty.
As for useful the C-17 and C-5 only deliver 1 or 2 tanks at a time. Get's the job done.
