I exchanged emails with the Mammut Rep JP about this. They do not recommend that action at all. Part of the problem I think is that the hose could get yanked instead of the handle in an emergency. Otherwise I don't really see it affecting the performance of the bag. This is one you'd have to make a decision on yourself and it if it goes south, could have serious ramifications in regards to the bag deploying or not. I *may* go that route, but not before I try a lot of other things first. Right now I've wrapped my already insulated hose with insulation tape for water pipes. It looks like shit, but if it works, I am cool with it. I don't suspect it will work though as the should strap rides high and tight to your body, getting insulation from there too.
