I included the four Mycenaean samples (I9006, I9033, I9010, I9041) and the Armenoi (I9123) one in a Eurogenes K15 PCA, and that's what came out. The purple ones are the Mycenaeans, the circled purple is the Mycenaean who got the Samaritan result, and the gold one is the Armenoi sample.
Regarding the western-Jewish/southern-Italian/Cypriot/Cretan affinity, there was an interesting discussion here, https://anthrogenica.com/showthread.php?14484-Could-Western-Jews-(Ash-and-Seph-)-descend-from-Aegeans-and-Levantine-admixture, which you probably already know of. Haven't gone through much of it, just 5 pages, but still some interesting ideas.
