It probably has but i've never seen it. Hitler's Meditterenean Strategy probably counts but Barbarossa still happens in 1942.
There are other ways to take Britain. If German concentrated al its efforts on the Med along with Japan in the pacific and an all out Luftwaffe blitz the British could break.
And the Americans and Russians are doing what, precisely?
If Japan attacks in the Pacific, its going to be the Americans first, so the USA is involved - even if, given this assumed more activity against the UK, a shooting war hasn't broken out in the Atlantic already...
And just how long will it take the Germans to ramp the number of U-boats significantly up from their OTL buildup? I dont think they could have increased the number much before mid-42, they are already in a huge U-boat expansion program. They could build more surface ships, but these take far too long to build to be useful.
And Stalin was planning to attack Germany - a Germany involved in the west in 42 would be ideal for him. Especialy seeing how many planes the Luftwaffe would lose in a 2nd BoB...and the tanks the Germans arent building because they are buidling ships...and the forces sent to the Med (where British subs will happily sink everything that comes their way...)
While it may look good on paper, the UK-first option actually isnt a good option for Germany, because they cant trust Russia to sit around and do nothing. Also, in 1941 they are actually going to have to find the hard currency to pay the Russians for all those raw materials they've been getting..oops, they don't have it..!
