Removing a Remote Network from a Site-to-Site VPN

I feel I have to apologize for the basic question but I do not have access to any lab equipment to test this for myself.

When I remove a remote network from a site-to-site VPN will it bounce the tunnel?

To give a little more background, I have 3 sites we can call A, B, and C.  There is a tunnel between A and B and a tunnel between B and C.  All the subnets in site C are listed as remote networks for the tunnel between A->B and all the subnets in site A are listed as remote networks for the tunnel between C->B.  This means for a user in site A to access a machine in site C they must traverse the A->B tunnel into site B and then again traverse the B->C tunnel finally into site C.  What I am attempting to do is build a tunnel between site A and site C allowing for traffic to go directly into site C rather than needing to travel through site B. 

I know that I can just build a tunnel between site A and site C but when I remove site C's subnet from the remote networks of the A->B tunnel will the tunnel need to be rebuilt?

Thank you!
