Another interesting idea.
I do not think it is going to work out though. Lets say the UK buys its carrier and 2 trans in round 2. The US places its fighters there and 3 trans in round 2 as well. In G3 germany hits it with 4 fighters and a bomber. The most likely result is that the allies retain 1 transport and their fleet. The next most likely is 2 transports, then 0 transports (23%, 19%, 18%). Going with the most likely as I always do for examples, that leaves the UK with 1 AC and 1 transport. At this point there are 6 troops on the ground in finland/norway, all US. That’s not really the bad part though.
The bad part (and note that I don’t usually strongly advocate pearl, but in your strategy it would be very beneficial to do so) is that you cannot hit pearl. You lack the airforce to do so, and you lack the navy because you need to go hard into asia if you are not going to be using your airforce on offense. In UK3 the UK builds lets say two more transports, and the US rolls in with 3 to 4 transports that unload in finland. The US ALSO rolls in with a carrier, fighter, sub, transport, and battleship. You can barely even dent that force with Japan.
So what is the net result of this strategy? You killed 2 transports the UK was going to use to load troops in UK3. So in round 4, the net is that all of your airforce is dead, and you stopped there from being 4 troops in europe. All of your airforce is dead. You do not interrupt U.S. supply lines because they drop off troops before you can kill them. Without your airforce you will have a harder time solidifying in africa, and it will take you until about round 3/round 4 to be raking it in. However, at that point you have no airforce, a nice tradeoff for the allies. If Japan isn’t moving to take out the remaining navy, then the allies can plan on hitting africa after your airforce goes away on round 3. If germany does not take out the allied navy, then the allies can move the navy to algeria anyhow on round 3. The UK could also just neglect to buy a carrier at all waiting for the US to show up, and do other interesting strategies which I will leave as an excercise for the user.
Lets take your strategy against a very typical UK opening. It builds one carrier, 1 transport. The US flies its planes in as well as one transport. Germany attacks and brings their air force down to 1 fighter and 1 bomber, eliminating resistance. The next round they build 1 carrier and 1 transport, and the US lands 1 fighter from hawaii and moves in its 3 transports built on round 1. Indeed, the UK can just taunt you and build 3 transports, and likely survive with 4 transports (3 built + 3 from US). Assuming you continue your kamikaze mission of destroying the navy, the end of round 3 has the UK seas with 4 us transports (built last round + hawaii), 3 uk transports, 1 carrier, 1 fighter, 1 sub, 1 battleship. If you sacc japan against that you will kill off all but 2 transports probably, and that is assuming the UK is not landing 1 of its fighters on the AC. The UK would because it has little to fear from germany taking karelia, without its planes and all. So as above, lets take stock of the situation at the end of round 4 and what you have accomplished.
You have kept 2 infantry out of europe the second round. In round 3, the UK drops its full load because you only killed US troops. In round 5 the UK dropoff is cut by two because you killed 1 of its transports. So the total for both of these is that you delay the arrival of 4 troops in europe and delay an african landing. Your attack on russia is severely weakened, your march across asia stalled, and your airforce is completely dead eliminating flexibility and defensibility of your forces.
It is an intriguing idea, but I think in practice it will fail, miserably.
