You know what would be nice?
If Wheels Mfg would make direct mount versions of their hangers for more recent bikes... The double hanger with two mounting bolts situation is just awful.
Probably not part of the problem here, since it's so widespread and isn't known for causing these dramas, but it certainly wouldn't help.
Anyway, I'd look closely at how the hanger connects to the dropout, as FB suggested. From your pics, I can't see any reason why one bolt should sit further out; maybe start there.
