I don't really think there is any demand for that. The generated WASM code is already optimized. The JIT is basically a very fast AOT compiler. The only advantage you're gaining is faster startup time and that could perhaps be achieved by caching the generated machine code on disk.

I compiled a GB emulator written in WASM to Rust yesterday and benchmarked it. The Rust one was about 7 times faster.
