If nothing else UW should be able to hire an advisor.
You know, I was thinking that all war teams might be better off with 1 extra player who doesn't play. So if you want 8 matchups per team, they'd have 9 players with one non-fighting member.
War has a fair bit of overhead, making spreadsheets, testing decks, analyzing opponents etc. So early in a war, this leaves one extra person to set up stuff like this and get the teams set up without interfering with the players testing/preparing for their own matches.
Later on in the war, when someone on the team leaves, this 'extra' player, becomes the first replacement player. So if a team has 8 fighters, and 9 players, when someone leaves the team permanently, the 9th player takes their fighting spot, and the team loses their extra spot as the penalty (instead of a card penalty for the first one). It's sort of like having a spare player for something that seems to happen a lot. Teams that don't end up needing a replacement, retain an advantage of an extra builder/tester/whatever throughout the war.
This extra player could also double as an extra sub (with the salvage penalties) for hard to arrange matches.
