Yes, that will work!!
It works in all cases where turning the ring on is not the last thing you do in the round and the last thing you do is not a free action!!!
Note: I think we are getting close to a breakthrough...
OK...
So assuming that you arrange your fighters round similarily to the above noted spellcasters, why can't a greatsword wielding fighter turn the ring off, attack (std.), turn ring on, move, END TURN?
