Are Romanians the most phenotypically diverse Europeans?

In looking at pictures of Romanian crowds, I saw people that looked traditionally Eastern European or "Slavic," others that looked typically Mediterranean/SE European and akin to Greeks or southern Italians, and even some who looked vaguely Central Asian or Turkic/Tatar. I also saw Germanic looks and generic Western European looks as well. With the possible exception of Russia (because of its sheer size), I don't believe any other European country contains locals who run such a wide gamut (although France and Italy come close IMO).

I have also read that their origins are not completely clear and that it has been generally hypothesized and strongly believed that their origins reflect a mixture of, among other groups, the indigenous Dacians/Thracians, Roman soldiers and colonists from all over the Roman Empire (hence the name and Latin-based language), Goths, Huns, Slavs, Bulgars, Magyars, Cumans, and Tatars. I think that the combination of the diversity of the Roman citizens who settled the land, along with the many waves of invasions/migrations, explain this wide spectrum in looks.
