I don't know about "should", but I've never had a problem moving VC cabling
around, unplugging, plugging. The cables aren't "smart"  (AFAIK), so its not
like the box can detect if a VC cable gets attached, only if there is something
on the other end.

I would expect changing from standalone to virtual chassis would be a
service affecting change though, so be prepared to stop passing traffic if
this isn't done in a maint window.
