Your proposal sounds nice, but HOW?
First, there will not be any “excess revenues” for awhile, until something changes.
Where on Earth do you propose we PUT any “excess”?

You either buy govm’t bonds or stocks and do people really want the Federal Government owning huge swaths of the private economy?
