Is it possible that, at some point durring the collapse of the Ottomans in the Balkans, all the areas of muslim majority (Albania, Kosovo, Bosnia) to be a single state?
Would be pretty difficult. On the one side you would have Bosniaks who need to establish a clear and fair division of power with Croatian and Serbian populations, something that it is very difficult and does not function even today ( Yes Dayton, I'm looking at you!).
On the other hand Serbian/Albanian population Kosovo mix would have to be considered in the same way.
The key of geographical linking to those two populations is in the Sandzak region ( northern Montenegro/Southern Serbia ) where a good bit of muslim pop. lives as well.
So if you could have an equal power division between Bosniaks and Albanians with Sandzak serving as a communication bridge between it may function a bit, a BIT. And even then you would have an eventual emergence of Albanian dominance since they outnumber Bosniaks in ratio 2/3 to 1.

You can unite Albania, Kosovo and a part of Macedonia where the albanian population had a clear majority but Bosnia is too far away and it is different by language and traditions...
