It's a nice idea because there's certainly a lot of inefficiency in the federal government, however I'm skeptical a separate external commission of outsiders (no matter how smart and motivated) will be able to accomplish much in the ~6 months it will exist. Senior career bureaucrats inside large federal agencies are apex grand masters of manipulation, camouflage and political hostage-taking. They'll deploy malicious compliance, weaponized policy farming and media leaks in ways so viciously devious it'll make Alien Xenomorphs look like Care Bears.
