There is no disadvantage, people do it all the time. Even tele people (but then you have to ask yourself why you're teleing in the first place if the gear is so heavy ). I am skiing some Denali XT's, Freerides and Atomic R:ex and it is dang close to an alpine setup But many feel their skis downgraded in performance even w/ the Freeride binding. I'm not a good enough skier to really tell and have spent little time on alpine setups. AT boots will always introduce some "noodleness" to the deal, but the denalis can really be cranked down. The whole setup weighs a ton in relation to my tuas and silvrettas, but when I just want to ski for skiing, it's like driving a mack truck.
