It s difficult to predict anything conclusive. I know Albanians used to be very aggressive towards foreigners settling among Albanians. These lineages would need to have come very early or have come as Albanians. I imagine the Diber area would have more exotic Y-DNA because it was often the scene of major battles. Although these soldiers were usually Albanians themselves, I imagine not all were. This might explain the increase in I1 and R1a we are finding in the area in comparison to the general Albanian population. The other reason I'm leaning towards this scenario is that these "exotic" lineages just don't seem to be related to one another.
I could be completely wrong.
