Yes, restarting varnish (completely: ie both manager and child process)
should recreate it with no side effects.

Varnish doesn't spend long time on startup, so I would just get it
done and over with.

(In the meantime, if you have enabled the telnet option, you can still
see the stats through the CLI interface.)
