"You tasked me with translating this scene, so since you gave me a general programming language I used a buffer overflow to break out into the animation engine and animate your characters to use sign language."

Jokes aside I don't hate the idea and is actually quite positive to writing translation in code. I am a bit questioning of why you would need a new language for it though, why not use an existing programming language?

As others pointed out here the biggest downside I can see is that it would be harder to outsource.

Well that's the point. It's not anything new at all, just the plain JavaScript/TypeScript/TSX you already use. No extra tools are required either; TypeScript and a good editor like VS Code handles it all.
