Re: Sound Change With Labialized Consonant Codas

I'm not sure if you're looking for diachronic or synchronic production, but
vertical vowel system languages of the Caucasus such as Abkhaz might count?
Those have labiopalatals triggering /a @/ > [2 y] (according to WP...) Also
not sure if "labiopalatal" means /pj)/ or /s\w)/, or if it works backwards...

I was going to bring up the funky allophonic difthongization /i E A/ > [iu
Eo Ao] in Seri (gess I did now, too), but then I noticed you specified
*front* rounding. Still, the first two look like they could easily go
further to > /y 2/ so yes, the idea strikes me as quite natural, especially
if you have a language with coda labialization and neighbors with vowel
rounding.
