Realms+ (More player slots)

My friend has a Realm with over 300+ members, but it caps at 10 players, so there isn't a lot of room for big player games like a battle royale game, with over 30+ players. So, my idea is for a Realms+, with increased player slots (30 maybe). I think this would be good for the community for easy servers with more players and you guys since you can increase the amount of money by about 3 times.
