I wish something like this existed in Turkic languages. There's a billion of them with very small communities, so it would be nice to see some of their properties preserved in a unifying language. Not to mention there's also a lot of documented, but dead ones, mostly because of communities integrating and taking on a Slavic language (mostly Russian and Bulgarian, name of which probably comes from the nomadic Turkish tribe Bulgars).

Many Turkic-language-speaking communities are getting influenced by Turkish or Russian, and given that Turkish being heavily influenced by French, Persian and Arabic in the history, it feels like the languages are losing their essence.

I know the whole deal with spoken language development as they borrow, grow, die and stuff but just like sometimes people want to code in a much simpler programming language / framework, I also have the dream of inventing a toy-but-maybe-even-useful Turkic spoken language.
