By the way, one more thing that needs to be changed is the transcription of Russian Cyrillic into Latin script, which should be entirely phonetic, to prevent atrocities like "Khrushchev" or "Yushchenko". Also Latin "k" looks less aesthetically pleasing than Cyrillic "к", so it should be rendered as "c", like in Irish or Romanian. Should be Hrooshof, Iushenco, Moscva, Crasnoiarsc, Cremlin etc.
That's what I meant to imply about the kyrillic script, not very seriously of course

The thing is Cirilic is super super effective for rendering Slavic phonetics
and retaining etymology (well not so much for Belarusians, but they do it on purpose), which is a fun addition. It is strictly one distinctive sound per letter, it contains no excessive diactric signs (only ё and й

and it looks interesting.
You try to adapt Latin to Slavic phonetics, you get things like
Czech, Szczeczyn, vrt and so on. You get a ton of different adopted alphabets with varying degree of ridiculousness, which are still unreadable to unprepared speaker of other Latin script based language. "C" can be read in dozen of ways, as well as "Y". So if it doesn't help foreigners to read it outright, then what's the point? There are some sounds foreigners would have hard times to pronounce anyway. Most of the English speakers for example can't produce palatalized consonants. Also the sound that is rendered as "ы" in Cirilic and "y" in Polish. And also the difference between ш and щ (sz and szcz in Polish).
And most importantly - Cirilic was made by God personally, and He inspired the Holy Fathers of Preslav school in Bulgaria, who put this divine enlightenment in written form. They all were later beatified and thus approved by St. Peter. As opposed to Latin which was combined by the pagan Quirites. God's opinion on Latin script (and I quote): "Meh".
But seriously, Latin script is great. For Latin language. Which I fully endorse as the world-wide lingua franca. But keep your dirty hands away from the divine gift of Cirilic alphabet, which is a all progressive and cool-looking.
