I read ages ago that it was possible.
Yes off-set is a problem, but IIRC you need Mk4 calipers / carriers and some proper spacers - not just washers - 6mm seems to jump out.
But if you are doing this why limit yourself to 288 when you could have 312 diameter, only difference is the carrier -best sourced from TT with the calipers.
I would have done this to my valver, I had spare calipers & carriers but I run RX2's space is at a premium and would have had to go up a wheel size.
