I did an experiment about a year ago when I re-wrote part of LiveScript's code emitter to produce a babel-compatible AST rather than javascript code. It would then pipe the AST to babel's generator and produce the final JavaScript. The benefit was that I could then use any babel-compatible toolset and still write code in LiveScript. ESLint worked with almost no tweaks necessary. Theoretically, you could also use Flow and TypeScript with this approach. Anyway, I didn't have enough time to finish the project, but somebody took the idea and did most of the work [0].
