Were we? This chain started with the idea of getting rid of the concept of the president and moving to a parliamentary system. Then it shifted a bit into giving the judicial branch its own law enforcement agency.
Those both risk creating a constitutional crisis, not avoiding one.
Amending the Constitution to create a judicial law enforcement agency would not, in itself, be a Constitutional crisis. Or if you meant that such an agency could then cause one, yeah that could happen in theory, but so could the Executive causing a crisis because the courts don't have an enforcement arm. And to act like the President causing the crisis isn't the more likely scenario in 2025 would be stupifyingly ignorant.
