Here's the question...
If, as you say, ACA becomes null and void, then there is no law for McConnell to add four words to to fix. He has to start from scratch with a new law. Is that going to be the likely interpretation? I doubt it. McConnell will say that rest of the law is valid and they will fix it.
However, another thing that is not in the law is severability. Congress purposely took out the severability law, just like with federal exchange subsidies. Is SCOTUS going to act as if severability were still there anyway? Will McConnell? Will lack of severability cause SCOTUS to toss out the whole law?
I think that one of the reasons that Roberts twisted himself like that was because of the lack of severability.

The ruling would impact the subsidies which, as the referenced article states, would effectively financially destroy the law. The law itself would remain, but the subsidies would be struck down. In that case, McTurtle and the rest of the traitors would absolutely be able to add a few words and fix the issue, I would assume. However, the fact is that getting rid of the subsidies in states that DIDN'T create exchanges would cause millions to lose their coverage overnight, essentially. Enter single payer.
