I would be extremely careful to dismiss this out of hand. The group includes a large number of people from the Trump administration team, and the main purpose of the plan is to reform the government through loopholes/grey area means to consolidate power in the executive branch - thereby allowing rapid and sweeping changes throughout the government as a whole. Trump would love that, and has sung the praises of dictators and openly said he plans to be a dictator "on day one".
The system isn't designed to handle anything like that, and a ton of damage could be done by a concentrated effort from a group that intentionally refuses to play by the rules/norms.
