This is pretty much what we all do here now!! Id be willing to bet if there was a chiller just laying around it would have been brought to you!!

As scubasteveo said there are just too many "ifs" as well as a central location for it to be stored when not in use. There is also the issue that I am sure would come up and that being that "one person" might not have it available to them when needed and to put it simple crab about it!!

Its not a bad idea, but I can see it causing more problems than it might be worth.
