Yes, but...
...the OP is a member of one band who's taking part in a larger parade. His band's action for next year should be to ask the overall parade organiser for details of what planning has been done, what has been agreed with NR, and copies of the agreed procedures for each band to follow. It makes no sense for each individual band to come up with their own plan, and contact NR separately (unless of course they have concerns about what they hear back from the overall parade organiser when they ask them)
