It's a bit naive to think that the clientele will radically chance based on the re-branding... afterall the big money comes from, guess who, rich housewives and wealthy businessman (and this is not only in places like Dior or YSL... I usually see old ladies shopping at more 'edgy' multibrand stores or places like Celine, Balenciaga...).
SLP won't only be sold in paris, london or la. Most of the cities that have a SL store even lack that rich it-girl / socialite / rockstar whatever type that this could interest. Speaking from my own point of view, living in Rome and working in the business, i know where the money of these big stores come from, and its not from a young clientele... that's only a small percentage (if any at all). I don't also foresee the company firing their old employers (what's wrong with an old s.a. by the way? they're always the best at their jobs, helpful, knowledgeable etc) to have punk rock skinny kids welcoming their years-long clientele. I know it would shut down immediately here... and i'm pretty sure in many other places.
This approach might work in hip cities but that's an irrelevant part looking at the big picture. Sure they could impose this new 'thing' but would it work? I doubt it... not everywhere.
