The printed chairs are an eyesore. I would love to have it reupholstered just to fit in with the other couches.

Love the fourth picture. The chairs in the corner look lost, I would move those chairs where you have the opening and add some green pillows to the two sofas, then you would have the perfect space.

I like the printed chairs. They give another dimension to your room. I personally would not reupholster them. I like both of your arrangements. What if you did something different with the window treatment. Maybe that is what is throwing you off. Perhaps stationary drapes on each side, and some sort of a shade/blind for window covering. You could also try a larger carpet so that your furniture is pulled back some from the fireplace and then have the loveseat on the window wall, the couch on the long wall and the 2 chairs across from the couch.
