Celtic People of Briton - what did Ancient Khumric sound like - Breton via Egypt?

…so, what did it sound like, the Khumric Language or Language of Ancient Briton or Language of Etruria via Troy via Syria via Chrestianoiland and the Scattered Ten Tribes of Israel via Egypt and all that Bible-y Babylonian jazz-mix.

‘In the noble land of Syrie th[er] was a noble kyng and mighty and a man of grett reno[u]n that men called Dioclitian’. The story continues with the 33 daughters of Diocletian, the eldest named Albyne (Albina), who murdered their husbands and were set adrift at sea before they landed on an island, which they named Albion. [source BRUTS OF ENGLAND] attributed to the supposed first real invasion of Britain by the Syrians in AD 1500, followed by a further invasion in AD 500 by Brutus of Troy.

KHUMRIC: it’s an ancient ‘root’ language that’s said to adhere to the Coelbren Alphabet and is said to share distinct grammar markers with ancient Hebrew/Aramaic or Khassite, deriving as it does from Biblical Egypt aka The Fertile Crescent of Eden-myth and so on ad infinitium. And while this supposed Holy Grail of Ancient Britonic/Bretonic/Brythonic Language (the Coelbren Alphabet) accurately translates into pre-modern Welsh, can it really have been spoken with a Welsh accent?

In the same way that modern Spanish language organically developed a lisp, when compared to older versions spoken in Latin America, did modern Khumric or what-became-Welsh develop a similarly affected Thh~ (as in Llan~ or Clan) that it never before had? I would love to hear a Ll-less reconstruction of this ancient ‘root’ language (Welsh with an Arabic or Scythian/Phoenician accent) if that is what it is, are there any researchers out there working on such a linguistic project?

In case you’ve never heard it before, here’s the decidedly-Dutch sounding Breton language, as still spoken by several old blokes in Brittany on the western coast of France. It starts off in French, then it gets Dutch-weird… I’d still like to here a pre-European reconstruction of Khumric-of-Egypt accent if anyone cares to do that insane a project.
