I am probably wrong about 27 because I'm thinking of the 27th amendment. But the point is that the It was already ratified by a bunch of original states in the 18th century. Some of the most liberal one.

There are no taksies-backsies for this, no statute of limitations.

And we already have a precedent where the original second amendment was ratified as the 27th https://teachinghistory.org/history-content/ask-a-historian/21861

Edit: already ratified by the following states:

New Jersey: November 20, 1789
