You could try cutting out the chainstay bridge?
Oh...??? Any other ideas? Please?
Sorry that was a bad joke - see a few pages back with images of people suffering catastrophic frame fail from cutting out the chainstay bridge. Jokes are confirmed bad when you have to explain them. I have nothing useful to add on this topic.
