I agree with UBE quilting. If you are going to use several fabrics, make it many or just one. IMHO you are getting too hung up on will it go or not. More fabrics is the answer or one fabric. If you can't see it from the back of a galloping horse, it's good. I used to be very controlling about my quilts and am not any longer. I use many, many fabrics and my quilts are raved over and I've been complimented, so it's not just me that likes them. Since you are using one fabric for the blocks it will have a unifying effect while using your greens and you would be surprised how well greens go together and with that lovely main fabric it will be a hit. I'd go to my fav lqs and buy fat quarters and small cuts and mix it up.
I've made several scrappy green and neutral quilts and many greens go well together - they do in nature, right?
