There are two numbering schemes for the GPIO pins. It looks like you are using GPIO numbers rather than physical P1 numbering. In that case it should not be a problem as long as you don’t plan to use the rain sensor connector or the on board relay.
I would be interested in learning about your rs 485 application.
