Galliano? Nooooo don't touch my Galliano!!!
Oops sorry my possessive side took over. *whacks possessive demon away into oblivion*
Anyway, being relatively new to fashion, I doubt my suggestions make much sense but I'd probably make the following changes:
1) Louis Vuitton / Marc Jacobs => Louis Vuitton / Tom Ford
2) Emilio Pucci / Matthew Williamson => Emilio Pucci / Christian Lacroix
To explain, I'd get rid of Marc Jacobs because frankly, his latest collections are somewhat lacklustre - minimalism in fashion is simple yet artistic and wearable, but Marc Jacobs' minimalism for Louis Vuitton is plain - too plain. Tom Ford established Gucci as sleek and sexy and I'm sure he can do something for Louis Vuitton as well - it doesn't have to be p*rno-sexy, but he should be able to inject some sleekness into the simplicity that Marc Jacobs has set up at Louis Vuitton.
As for the change of Emilio Pucci's head of design to Christian Lacroix, it's mainly based on the fact that somehow Matthew Williamson doesn't seem to have much individual flair and style as Christian Lacroix. I guess I sound very pompous (indeed, I am not very familiar with Williamson's works and have only seen a handful) but I believe Lacroix can make Pucci elegant and classy (and classic, as well).
