Cross-linguistic idioms would be interesting to see. I suspect it has a lot more to do with the etymology of the idioms than anything else. For example, I know that the idiom "I'm a big boy" (meaning "I am capable") works in English and Russian, but in Turkish it comes out sounding more like "I'm a large child". Actually, I found lots of idioms are identical in English/Russian (there are some unique ones to each language), and I suspect it comes from a shared European ancestry.
