I'd be a bit more concerned at the extra stresses on the QR skewer (effectively doing the job of the axle but certainly not built to do so). Not a safe 'repair'... at all. Fine as a get you home bodge but otherwise really dodgy. If that is the only way to fix it then I'd say that frame is a goner.
Didn't Klein's come with a non-replacable hanger? Stiff but game over for the frame if it breaks (which this one appears to have).
EDIT: Yep, it would appear they did/do (or at least this one did):

I guess you could try and magic gear it like this one.
