I have some doubts about your Albanian nationalist scenario. It could have worked, but it would have required really big Allied support. What is more important, the communist would have had only to last till Soviets' arrival - after that Red Army takes care of BK and installs puppet goverment. And the Albanian civil war can not be decided before that, because Albania is still an occupied country. Later the Soviets, as "liberators" of Abania have a decisive voice. They claim BK to be "reactionary fascists" and destroy them.
I know, I know. The Allies are more powerful in TTL, but somehow I doubt they would be willing to fight for Albania surrounded by other communist countries. I already went a little too far pulling Red Army from Poland.
As far as Germany goes, I didn't mean splitting it into communist and non-communist parts. I meant dividing Germany into many countries, like it was before 1871: Bavaria, Saxony, Brandenburg etc. Here I'm still not sure. The Allies are stronger, they won the war quicker and with smaller losses, so they might be not so mad at Germans as in OTL. On the other hand, with neutral states as a "buffer" against communism, they don't need strong and democratic Germany, and calls for vengeance would be strong anyway. It may be even a part of Allied-Soviet deal: Soviets would love to see Germany divided and demilitarized, because it weakens the West. It might be the price for leaving "buffer states" alone.
Your suggestion on the division of Germany into many countries is quite complicated...and not a distant idea. There must be a strong separatism (much like the US "states' rights") among the leaders of the various Lahnder of Germany, and no party must be able to gain national support among the Germans. in short, the allies must ensure that no party or political movement pursue a "german reunification" agenda. in fact, there is a chilling aspect of your proposal; it might lead to the creation of several "extremist" political groups with the goal of reunifying Germany, which may lead to an early rise in neo-Nazism.
As for the Albanian scenario, NLF lasting until the Soviets arrive is not part of it; here, the soviets manage to reach only romania & bulgaria (and manage to supply their stooges in Greece and Albania). what's more, the creation of a soviet satellite in the form of Albania would somewhat "disrupt" the West-Soviet balance in the balkans. a better scenario would be a titoist Yugoslavia, nationalist & neutral Albania, and western-leaning South Greece (Kingdom of Greece) against the communist satellites of romania, bulgaria, and North Greece (Hellenic People's Republic).
kinda makes me think of revising the "balance" farther north...
