My concern is actually not so much the weight as it is the fit to the rim; i.e. would a typical 1.5" tire be too narrow for rims currently running with 2.125"? Unfortunately, the local bike shops pretty much don't want to deal with you if you're not buying a $5000 carbon frame - ask about a 20" tire, and I'd probably be laughed out of the shop. ;-)
