I think some people are missing the point. GB have no chance of winning, so why not blood some up and coming improving riders?
Cook and Worrall would be top of my list, Harris has the experience both as a rider and an advisor, Woffinden will keep the score respectable.
Kennett (and he's not alone) is a proven flop, and very unlikely to improve to WC level. I would have picked Barker ahead of Kennett, at least you would get 100% effort from him.
