Maybe some modification of the trip plan might work out a little better for all concerned "Sherpa’s" included.
Maybe fly-in/ tow in to one of the lakes the Native Peoples have boats on and set a base-camp as far away from the landing site as possible.
You could plan your base-camp and day fishing lakes using this tool here:

That way you can set a nice camp and not have to worry about breaking down and moving all the time.

Then plan day-trips to lakes all around the base-camp lake.

While the Sherpa’s are running the empty canoes/day packs across ,the others can be fishing until it's their turn to cross over.

3 in and 3 out and multiple camp moves leaves little time for just fishing and will put a lot of strain/stress on the Sherpa’s trying to please their clients.
