It really doesn’t matter how many people like the quilt...you don’t. I agree with you that the different border size is bothersome. If it were me, I would take the binding off and cut the wider the same size as the narrow one plus a seam allowance and then reattach the binding.
If you can live with the dark green that would be the easiest fix. If you really can’t then you have a lot of deconstruction to do. It is fixable if you want to do the work or get someone else to do it depending on your budget. The embroidery is lovely and you should be able to show case it the way that you choose.
