Exporting volume sets to hosts is evil and nasty
that aside ... you could cludge your way around things by ..
1) Export VV-mistake to the host set a 2nd time, with a high LUN ID (say 100)
2) Rescan for storage on VMware, vmware should treat the extra LUN ID to a volume it already knows about as extra paths.
3) Un-export vv-mistake from LUN ID 27 on the host set
4) Rescan
5) Add vv-mistake ot the volume set, it should go in as the LUN ID you are expecting
6) rescan
7) Unexport vv-mistake from host set LUN ID 100
8) rescan
