I think that's a great idea! Although you might need a bullhorn for them to be able to hear you from all the way over there. I did something similar with a 300mm lens on the 20D once and it would have come out great if I had used flash to balance the light. The hardest part may be getting sufficient depth of field for the background to not be a complete blur. And if you stop down a lot, then you'll need pretty powerful flash to help balance them with the foreground. But the mountains in the background don't have to be totally sharp, either -- as long as you can tell what it is, a little blur will help focus on the people anyway. Aside from that I don't have much advice, sorry.
