Is it OK for a six ball to play in a greensomes competition ie 3 pairs?

In a greensomes competition, each team consists of two players who hit alternate shots. Typically, the format is designed for two pairs, making a total of four players. However, if a six-ball is being used for fun or in a casual setting, it could be acceptable as long as all participants agree to the modified rules. In official tournaments, it's best to adhere to the standard pair format.
