I like the idea of it. Even though he is no longer involved in the Ferrari F1 team he still has a contract to help develop their road cars. Could be a bit of a conflict of interest which makes me think it is unlikely. Still, who knows!
Great to see Schumi back in Formula One. I have to admit i always had my fingers crossed he would retire at every race when he was at Ferrari, but i have sort of missed him a bit, and at least he is with Mercedes now so thats better.
