Yeah, I like the concept of UKP & ANZAC economies (and pieces?) merged. It was a key feature in a house-ruled version I was working on years ago - didn’t finish because balanced mod came along before I was done.
I’m sure somebody here will want to play you with your variation, just be advised that if you don’t finish 3 league games by 12/31, your opponent won’t get many points from you no matter how skilled and experienced you are,
BUT. Half of our players would rise in the rankings (if that’s what they’re interested in) if they prevail against you at your own game ;)
Some of the OTHER half would probably be willing to play you in league play despite the points thing.
But you posted in a great place, because there are about 40 active players here and if they don’t want it to count in the league, they may play you outside of the league and you still get what you want, I think.
Good luck, and have fun
