If your intakes are fixed to the body of the robot, which I don’t recommend, you can still get it to work by using flaps. Flaps will flex around the shape of the Change Up balls.
But a better way to do intakes is to make them flex in and out with elastics. Then you can do either flaps or use rubber bands covered intakes like 97963A, 95E, or 2775J.
Unless flaps that you have are new, flexible, and grip really well, I would do rubber bands, because you have more ways to tune how they grip with amount and kind of rubber bands that you use.
