I don't think, based on the room dimensions you listened that the speakers are too much. I have heard them sound unbelievable in a smaller room. I think you only need 24-26 feet for the bass to bloom properly which you excede.
Based on how good I heard the Salon's sound I would do what I can to hang on to those speakers anyway. The thing to worry about in a nondedicated listening room is getting the Salon's in the right place to get the best possible sound from them. It would really suck having a speaker capable of such fantastic midrange, but then not being able to hear it because they are stuck too close to the wall.
Good luck!
