Well I contacted Prodrive about a possible attempt to try beat the 2008 one they did but unfortunately they don't fancy doing it. here's the reply.
"Hi Pete, I was there, indeed it was me who was lining up the cars to spell his name! I think this was a one off tribute. A year on from his death, it was such an amazing event with such an incredible turnout following the convoy down to Banbury from Scotland that we could not and probably should not try to replicate it. For all those that took part, I am sure, it will remain in everyone memories for rest of their lives and was the best possible tribute to such an incredibly popular driver. "
