We do that rather often, Ron. In RMNP, where they require canisters for their 20 bears, my buddy straps the larger Bear Vault to the outside of his pack (I carry the tent). He usually puts some bulky lightweight clothing in a water tight S-to-S roll top, and puts that inside the canister. We both carry our own food, and at camp we transfer it to the canister. He takes the S-to-S roll top to the car wash to try to keep the outside reasonably free of any acquired food smells.
Keep in mind that Colorado doesn't have many "Yosemite" type bears, so things are a bit more lax around here. The few park rangers we've met on the trail were OK with our approach. Most of them know how silly their canister law is. I've never had an encounter with a bear here in 35 years. I've seen only one, and that was in my back yard near Boulder. I've just seen bear scat once. They're out there, but apparently not yet habituated to humans (totally different situation around the mountain towns though, as they've come to appreciate easy garbage cans).
And Eric, if I do meet a bear on the trail, I'll just give him a vegemite/Tabasco sandwich and tell him a few boring stories of my childhood. He probably will either quickly fall asleep, or else bolt for a more interesting place that offers better food.
