I don't quite understand what you mean. If you organize a game, I have a suggestion: 16 people are divided into two groups. How to group, you can freely combine the lottery or divide it into single and double groups according to the level. If you are all boys, you can have three doubles and two singles. If there are enough girls, it can be done in the following order: mixed doubles, men's singles, men's doubles, women's singles and women's doubles.
I hope I can help you!
