And it may be so, but the law/constitution doesn't automatically morph to adapt to whatever some particular person thinks is more efficient. If this is really needed, maybe it's time for a constitutional amendment adapt the structure of the government.
We can nit pick what you meant by 'automatically' morph, but the fact that it was just forced into a pretty severe morph to adapt to what 6 particular persons wanted I think challenges the argument you're making.
