I cannot see Roy getting his mind and even phenomenal reflex around a total package Usyk. What benefits Usyk too is he knows the later path Roy traveled, and he didn't do it as a one off, but rather dominated the weight range Roy was vs Ruiz first. And we have to talk about the elephant in the room..it wasn't like Roy fully completely "dominated" 175 either. There was a ton of politics almost setting the table with wbc and wba etc. He spent about 4 years there sort of running numbers up with his career high hbo contract and honestly it almost felt he grew a bit board to the point of signing the fight with Buster Douglas originally. In a way, he had hit his ceiling and not just weight wise. Usyk as southpaw way too shifty and wouldn't get sucked into the "awe" factor like a few did vs Roy. The straight multi punching and natural hand speed with both short and long constant angles and shifts of Usyk would prove a big bridge too far for Roy.
