I don't think so, since mounts must be present for the kernel
(and other systems) to know about them.

Flushing active RPCs and then leaving them in place would be
a better approach, as NFSv3 and below should be stateless, but
there are no doubt problems with this I'm not aware of, NFSv4
would probably have difficulties.
