Have you considered seasonal items? Current season has a chevron statement flap bag. Comes in 3 sizes, smallest size fits more than a mini and middle size fits more than a small classic. Not sure of US prices, but in Hong Kong the middle size was about same price as a rectangular mini.
Don't know if you had aimed your comment to me, but definitely sounds like good sizing and I like the Chevron pattern. Unfortunately, where I live there is no Chanel boutique and as Chanel is not sold online anywhere, I am stuck with 2nd hand/vintage options... :/
