Category 5 - HOW DO YOU PLAN TO GET YOUR AMENDMENTS TO WORK
That would be the category that says - If you are going to attempt it - explain to us how you are going to get a lawless post-Constitutional oligarchy to abide by new amendments to a document that has been already nullified, usurped, defied via precedent and rewritten by executive 'action'?
If you want to win support for the process and the cause, explain to us how you intend to get a lawless government to abide by them so the effort is not in vain.
DO IT
Which you followed with many of the concerns you expressed about the ability to have the new constitutional amendments honored in the teeth of a tyrannical government. You suggest that this is a new category but you are dealing with a new concept. My categories have to do with objections to attempting an Article V process. If you believe that it will not be honored then you need a new category which says "don't try it, it won't be honored" but you are on record as saying, "DO IT" but it won't be honored.
The degree to which it will be honored or dishonored depends on a variety of factors only one of which is the intransigence of the elites presently in power. Other factors include the degree and intensity of public support. We do not know and cannot know in advance how a post constitutional reform will play out in practical politics.
But we can "do it" and say to our children, "at least we tried."
