Just in case anybody finds the subject interesting and would like to play with this topic, there's an experimental native-Ruby JIT project by @tenderlove: https://github.com/tenderlove/tenderjit https://github.com/tenderlove/tenderjit (and the companion native-Ruby assembler Fisk: https://github.com/tenderlove/fisk https://github.com/tenderlove/fisk), which is (IMO) considerably easier to work with.
