i wouldn't mind. it could come into play when blue decides to close earlier than it should for the season or for weather related events (ex. camelback gets a lot more snowfall from a single storm).
i'd probably never use the option, but it could be nice to have.
... and blue will release more season passes.
This is grate! Maybe the Blue Mountain dog mascot and the Camelback camel mascot will make sexy time and we'll get a brand new mascot for both mountains.
