You could also send them the pics and politely demand a hefty % discount to avoid the return (don't even discuss an exchange initially because that kills your leverage).
See what they'll do (probably not more than 20%(and I wouldn't accept much less than that in your case), which does reduce the price a fair amount), then you can always talk about exchange later if need be.
If it plays like dream and things are near perfect from nut to bridge then that's probably what I'd choose,,,,but I kinda prefer things just a little bit ugly sometimes lol.
