Sea people establish themselves in Southern Europe

What if the raiding Sea peoples, ancient foes of the Empires of the old, establish themselves permamently in Greece,Italy, Southern Gaul, elswhere, dominating the pre-Indo Europeans and comeptite with Indo-European waves eventually ?
 
What's their population relative to the indigenous peoples of southern Europe?

I suspect they may ultimately be assimilated.
 
They certainly have, IOTL, some kind of relation with Southern Europe.
While a fair deal may have come from Anatolia*, there's little reason to doubt that some Greek (Myceneans or peripherical) and other Balkanic peoples (Proto-Phrygians?) didn't participated to the general movement (Aqawasha/Ekwesh/Denyen, etc.)

It's even quite possible that peoples from Adriatic, Ionian and even Thyrrenic coasts joined the bandwagon, as hinted by some names (Shardana/Sherden, Sekelesh/Siculians).
Some suggested Sea Peoples migrated to Southern Europe, but I find this theory less convincing.

I strongly suggest : "The year civilization collapsed" by Eric Clide, about Final Bronze Age and the possible role of Sea Peoples (but as well climatology, political structures, etc.).

*Keeping in mind we're certainly talking of more than one wave : Ramsesses II already had a "Sea People" guard attached to his person, so SP coming from Anatolia may have been originated from other places.
 
Really hard to answer considering that we know so little about them, as others have said this could have happened. Hard to say the impact when their culture is so unknown

They most probably didn't have one unified culture, and like Barbarians of the Vth century, not only issued from different origins but as well hugely influenced by the regions they neighboured (Egypt, Mesopotamia, Hittits, etc.) at the point their ethnogenesis may have happened "on the road".

That said, when it goes down to names, to some material cultural features (depictions in Egyptian art makes really thinks about Agean features), etc....
An at least partial Southern European/Balkanic/Anatolian origin let little doubt.
