I like the idea.
Though you're right. It can stir up on students with different abilities. And it might be a bit challenging on how it can be carried out in the IC. But I'm sure it can work out somehow.
A class for training can do the trick. See how two students group together of somewhat similar abilities work together. Or like [@Cerces22] mentioned, students of different abilities can have separate different types of training classes.
