I've found a work around. As mentioned prior, player 1 can select their skin from the main menu and can pick from the entire pack not just the first 6. The issue comes when player 2,3 and 4 want to do this.
To fix this I had to launch minecraft as player 2's account. Select the skin they wanted from the main menu. Then closed the game and re-launched it as player 1. When player 2 then joined the game the skin they had chosen when they launched the game remained.
Note: player 2 will need a nintendo switch (free) online account. (Not a paid online subscription, just a registered account) and then this should work.
