I would consider consulting a behavioral therapist. They can help with the routines at home, e.g., implement visual schedules to help shape his behavior.
I also think it's hard to tell how a person on the spectrum will react to new stimuli. For example, the Mass Mutual documentary, "Autism: Coming of Age," showed a non-verbal young man with ASD who learned how to rollerblade:

OP, is there a plan for what will happen with your brother for the future in terms of living situation etc?
