I'm glad you're keeping it real. Making it mystical mumbo-jumbo would definitely detract from the timeline.
I think your right Dom, ASB is really hard to do well.

Yes this is a lot more like the development of Hinduism, where Indu-European religeous structures was adopted by the Dravids. I think we will see the Gothes join the Druids religeous structures, the question are what religeous lingua franca they end up with, I think Garman* will end up dominating thanks to it stronger position compared to Irish, through local rites will likely stay in local language.
**Linguistic I think Garman will be closest related to Low Frankish (Dutch and Flemish) rather than Friesian like English thanks to the Frank settlers and the continued contact with the Franks (as in OTL).
As you know, language is something I think about a lot in this TL.
The language of Ansalérga is Tengua Sacriva, an extremely conservative version of Primitive Irish, it's a written language (using its own alphabet), but is only spoken by druids in ceremonial situations or formal contexts. In 600 AD it is still just about comprehensible to the Irish-speakers of Ireland, where it anchors informal speech so it is much more conservative than OTL. In Eriu and the Irish colonies on mainland Britain, Irish has evolved closer to where it was OTL, as the Tengua Sacriva influence was weaker prior to 550.
The Gewissings are a mixed Brito-Garman group, who have largely adopted Garman culture. However, their Garman has been very structurally influenced by British and contains many more loan words than any attested OTL Anglo-Saxon dialect. Its noun case sytem has undergone a massive simplification, paralelling that which is happening in British (similarly to OTL). This will be the first none Celtic dialect the druids use, with texts by 585 at the latest (in the Irish alphabet of course).
Garman proper looks more like OTL Anglo-Saxon, though dialectically divided slightly differently, and with a very strong Celtic substrata in the dialect of the kingdom of Saexen, due to the influence of the Belgae. There are more Franks, but also more Frisians, so the balance is more or less the same, after dialect levelling, the whole thing sounds very much like OTL but with a few more Celtic words and a few less Latin
The outlier is the Frankish of the Iceningas (Norfolk and Cambridgeshire areas), which has not undergone the process of dialect levelling, as it was a purely Frankish kingdom, was settled earlier, and is isolated on its Western border by swamplands inhabited by largely monolingual Britons (albeit ones with little political organisation).
There is no great problem of comprehension between the three Garman dialects, but there are three clear linguistic frontiers between Icenfrankisch, Garmanisch, and Gewisgarmanisch.
In the Ansalérga context, Gewisgarmanisch will have the most importance, as it is the first to be written down using the Irish script.
