Money wise there is no reason to sell them as originals. The RM boots will likely be much more expensive than an original pair!
From a collectors view, it would be bad if they could be sold as originals. Relabelling is easy though, so unless RM emboss their brandname on the boots somewhere, I can't see how you could prevent it.
Personally, I'd prefer a spot on pair, including correct labelling. I wouldn't mind if the contract year on the label would be '11' though, that could be a tell. Again, easily removable though...
Anyway, good luck with the project!!
