In theory, you could probably teach it. I know a lot of agility handlers who can't get around the course due to physical issues, and so they teach a ton of distance and get by that way.
In actuality - you wouldn't be competitive. Agility training has progressed to the point where the top teams, even locally most of the time, are going to be very fast and accurate. Handlers teach both verbal and physical cues to tell the dog not only which obstacle to take (which could probably be done stationary), but how to take it. ie "If my outside hand comes up near the commitment point to this jump, take it in collection and wrap the outside bar for a tight turn". I'd be shocked if anyone could produce a super tight, fast, competitive round without being fairly close to the dog, especially on a USDAA type course, where things can get very tight and 'international'.
