Yes! I'm currently using copilot + antigravity to implement a language with ergonomic syntax and semantics that lowers cleanly to machine code targeting multiple platforms, with a focus on safety, determinism, auditability and fail-fast bugs. It's more work than I thought but the LLMs are very capable.
I was dreaming of a JS to machine code, but then thought, why not just start from scratch and have what I want? It's a lot of fun.
