The notion of amending the constitution in response to political dysfunction is a bit paradoxical, because dysfunctional politics are upstream of the amendment process. Dysfunctional politics will likely mean a dysfunctional amendment.

Some thoughts on resolving the paradox:

* If the constitution had been easier to amend in the 90s and 00s, perhaps some wise politicians would've seen whispers of the current dysfunction and passed an amendment to preempt it. Maybe there could be a "department of the future" that's trying to figure out how things could go off the rails and what amendments we could pass in advance to help.

* If amendment was done according to an entirely different process (e.g. sortition https://www.sortitionfoundation.org/case_study_america_in_on... -- essentially a citizen's assembly), that could solve the paradox. Especially if the new process was something slower and somehow less prone to dysfunction. It'd be like an additional check & balance. Sadly, we don't have much experience with sortition or other very different processes, and it seems risky to entrust them with something as important as the constitution. Maybe the rule could simply be that the legislature is required to vote on whether to adopt the changes that come out of the sortition process?
