As far as the modification idea goes, it's a lot of work for not much payoff. The front triangle coming apart means that most of the hard work has to be done.

I didn't read your thread in the fitting forum. The question I have is how much stack height are you going for? A lot of people are going with massive stack height, and for them a larger frame with a radically sloping top tube will work.
