the majority of a congressionally appointed committee

Congress cannot appoint a committee to do this.

It could be done through "such other body as Congress shall by law provide".

Congress cannot make laws. Laws need to be signed by the President.

Not all laws!
Congress can override a presidential veto and thus pass a law the President did not sign

This “commission, etc.” is just fodder for the Rat “crazies”, keeps them energized. Nothing will pass that will have any real force of law. It gives Rat Congresscritters something to point to so they can say, “See I tried to stop Trump!”.

I think your take had merit, but it isn’t written clearly to indicate the president must sign off. If he were in a coma, he wouldn’t be able to do so. So, the issue will be appointing a body according to already written law.
