A very arrogant statement there 747 F/O. I well recall many Prune experts saying the same thing about Bransons' idea to start an airline called "Virgin Blue" in Australia. Should have heard all the smart-alec comments from the 747-400 F/O type experts. I too suspect very soon it will happen.
Sure you could wet lease Virgin Atlantic in and call it a Virgin Blue flight. Probably couldn't codeshare though because you would be in breach of the 3rd freedom right (and Mr Dixon would scream blue murder).
But why would you want to? I'm sure the cost structure at DJ is by far better than that at VS. Why not sling a couple of spare ships DJ's way for them to operate?
VS still has a couple of widebodies idle in the desert don't forget!
