Surviving Keszthely culture

[Cuāuhtemōc]

Inspired by Alternate History Geek and LSCatlina's mention of North African Romance dying out in a thread about Coptic Egypt, I am curious of the possibility of the Romanized population of Pannonia surviving to the modern day, either as a minority population or an people with their own small nation. Due to the barbarian invasions of the 4th-5th centuries and the fall of Rome, there were estimated to be at most several thousand living in small, fortified settlements, working for the likes of the Gepids and Avars. I know it's a small number but other people have rebounded like the Hungarians or the Czechs. So what is needed for the Keszthely culture to survive assimilation and make it to the modern day?

Bumping for interest.

The big problem is that their few numbers isn't enough to prevent mutual acculturation with dominant elite.
Likewise Trever remained romance, linguistically speaking, probably up to a late date, their situation in the border was removed, making them surrounded by romano-barbarian population.

Critically as they were the descendents or former bounder military corps, and while their social role diminished, their roman identity as well (It's interesting that Keszthely romans survived as an another distinct group, this time of craftsmen).

You'd probably need a more important popular romanisation (as opposed to formal romanisation of municipes) and a more important developpment of Pannonian cities in order to create them an attributed countryside.

A more stable border on the Danube (maybe a lasting Romano-German kingdom of Italy) would help as well.
