What if Boromir had taken the ring?

[Beren87]

My entire thought process there was baced upon the occurence in the book when Frodo claimed the ring for himself at the entrance to Mt.Doom. In that moment the very footers of Barad-ur shook, surely one with a greater will and more power when claiming the ring would bring down Sauron. As Galadriel said,

In the place of a dark lord you would have a queen!! Great and powerful...

I think the key word there was "in place" as in the usurpation of Sauron.
