Could D-Day have been in 1943?

On the Western front I have not seen any scholarly work that suggests an invasion of NW Europe in 1943 was possible, mostly because the logistics would tend to say it wasn't. If the Mediterranean & N Africa theatre offences (Operations Torch, Husky and Avalanche) had not taken place than materiel for an invasion on a reduced scale would have been available, but Torch & Husky are also where the Allies learnt to conduct joint ops & the US Army learnt to fight & blooded its senior command element. Without this experience D-Day is likely to have been a very different tale.

Did experiences in the South Pacific campaigns contribute to the planning for the Normandy invasion in any significant way?
