Ribit - absolutley spot on question - and I believe it to be purely rhetorical (iotw: self-answering).
As I stated before, the courts, congress, and the potus ALL have routinely ignored the clear written meanings in the Constitution - and will continue to do so.
As I recently stated, this 'Balanced Budget Ammendment' idead is a really, really, really BAD idea - for the above reason - it makes no difference to the jackasses and assholes currently occupying our government (read 95% of all occupiers - both repub and dem ).
In light of that - your gut tells you two things:
#1.) Any 'new' ammendment(s) to the Constitution would suffer from the same 'ignoring' as the rest of the Constitution.
#2.) The potential for any NEW ammendments to bite us in the ass are HUGE.
Methinks that what you have outlined as a 'possiblity', Sire Ribit, goes far beyond being a 'probability' and ranks right up there with being:
1.) a foregone conclusion.
2.) an absolute certainty.
and lastly, but not leastly (sic) ....
3.) A "You better bet your sweet ass that will happen, baby."
