I play with ITST mod and those players can't be used in World Tour mode. But can there be a simple exhibition tournament where you can just make draw for 8 16 32 and 64 players?
It'd be much better that way, instead of trying to pick who should I practice with. Doesn't need seedings, prize money or any other nonsense. Just creating draw randomly or manually, since almost all players are equal in ITST mod. Kind of like Creating Cups in FIFA. Bringing all the best players and having a tennis party.
