It won't affect the current connections. You would need to close the channels, and discard parts of the EOF stack. I think you would also lose all the snapshots. I am not sure what would happen, but my guess is that this is not intended and "bad things" would likely result.
I am not sure what you are trying to achieve, but I would spend time thinking of a different way rather than trying to make his work.
