Replicate existing proxmox node to new node and rename

I'm thinking about buying a new node for my proxmox cluster, but i am running 2.1 and as everything is pretty stable - bar an issue with the SAN, i dont want to upgrade to 2.3 for a number of reasons.

is it possible to clone one of my existing nodes onto the new node using clonezilla, and then reseting the proxmox install? (change name, wipe out anything cluster related?)

any advice?
