Stuff like that, definitely. But whole hog McLaren? I don't see the need. That's the problem with F1 teams these days. There aren't a lot of companies that need a global and unified sponsorship campaign, primarily built on branding rather than product. And while there are those that would want it, they can't necessarily afford it. And for the select few that meet those requirements, F1 is suddenly competing with annual events like the Champions League or quadrennial stuff like the World Cup and Olympics.
Emirates is writing a title-sponsor sized check. But they're spending it trackside.
Whatever McLaren end up putting on the car, it will be a hell of a an achievement. The only proper title sponsor we've had since the recession is Petronas, and they got a supply contract out of Mercedes for their troubles.
