This was an easy fix for our two kids who can't stand to be near each other. Well, one of them can't which causes a cascade of issues but regardless. With a 14' highwall, each bunk end is a king. We made two "rooms" out of the other bunk by putting 3-drawer plastic shelves right down the middle under the shepherds pole. After we taught them to quit screwing around with pushing the drawers into each other (kids can be taught), it has worked beautifully for years now. The bonus is that it gives us storage for their clothes and other things and DS thinks he has a bit of a man cave on his side for when he needs to retreat.
It's all in how you approach issues and look to resolve them.
