Pronounced roughly /'mo.ɾə/?"More" would remain distinct and probably still spelled "more".
Roughly /de.sen'dɔn.tə/ in IPA then?Well in the vowel sounds I proposed, I suggested that "an" and "am" are pronounced /ɔ/ or in the non-IPA pronunciation, "aw". If that is the case, it would be deh-sehn-DAWN-tuh.
So kind of like Italian, where /ks gz/ > /s z/, e.g. English express vs Italian espresso. I wonder if Italian influence might cause x to be dropped in favour of simple s or ss even in spelling?I'm not sure, but x as /ks/ comes from Ancient Greek, so when those words are borrowed, the original pronounciation will be at least attempted at first, even if it might morph over the next 200-300 years into /z/ or /s/.
If old Spanish words with /ʃ/ in them were borrowed with x, this would cause x to represent /ʃ/ or /ks/ or /gz/ depending on the word, similar to Portuguese. If the above mentioned Italian influence causes loss of x as /ks/, that would leave x only being used to represent /ʃ/ in old Spanish borrowings. Maybe if /tʃ/ is retained, with ch being used for both /tʃ/ and /ʃ/, then x could be the go to spelling to disambiguate /ʃ/ from /tʃ/. So for example, Japanese Shogun might be rendered as Xogun.
