And now you have two happy pilots where before you had two stuck pilots.

It's done at other airlines, we just haven't implemented it yet.

And again, what would the company care if those two captains swapped? It doesn't change anything other than vacation. If your vacation is available in the new base, you keep it, if not, you pick from available weeks. It's very straight forward.
