Something like
this ?
I must say however that a more sensible and from a naval point of view more productive scenario would be Barbarossa being succesful. The resources saved and the raw materials gained would have been fed primarily to the air/naval fight, while the Wermacht was planning to turn against the Middle East or India. Presumably pro-axis neutrals like Spain, Portugal etch would have gone over to the germans as well making bases available.
If Britain falls then so does much of the naval traffic which can be attacked. You will have to edit a lot more stuff as well.
