It sounds like Albania and Bosnia ended up in a worse position than IOTL. Glad to see the Ottomans assert their power where they can; it’ll be interesting to see how long that power can hold.
The concept of a dual Albanian-Greek state is very interesting but runs into a number of obstacles, chiefly religious ones. Since Greek identity at this point is still largely based on Orthodox affiliation, would they want to incorporate a large Muslim region, especially one with extensive Turkish ties and influence?
And that's going to be the million drachmas question is it not? After all as late as the 1910s the concept of Greek Muslim was in its forming stages and in the end did not really emerge as the Vallaads and Turko-Cretans where in their entirety included in the population exchanges. How it would have evolved if things had gone otherwise (as they nearly did with the Vallaads) is interesting to say the least.
Which is why I think a dual monarchy and not a unitary state was the one contemplated by the proponents of Greek-Albanian cooperation.
