Ask HN: Can WASM be used as a means of sanitizing native code?

Title. Normally with sanitizers (e.g., UBSan, ASan, TSan) the sanitizer is implemented by instrumenting code to store information at runtime.

Could a WASM sandbox work together with a compiler to improve the performance of sanitizers? I am thinking that the WASM sandbox (which is likely more optimized than the above sanitizers) could run native language programs compiled to WAMS and maybe track information more cheaply at runtime than the sanitizer implementation could.
