From what I see KW has far too many teams for the space it has. My suggestion for that problem is to separate teams in groups of 4 or 5 all in the borders of a smaller hexagon and have them compete to get to one major monument in the center like a gold rush. With minor monuments around of course.
That would prevent a team HQ to be surrounded and have a major goal (very good VP on major) instead of controlling so many lands.
After a round is complete, the top 2 teams would go to the next round with other winning teams. Likely to the fight pits structure, until maybe the 3rd final round. Each stage could be something like duchess, prince and kings arena.
It would also give the chance to conquer bloodlands terrain more often until you have a hot battle royal.
That said, I do like your suggestion way better than the present event
