I would not mess with the opamps. The Model-3x were designed around the 4559, and it is a very sweet fit. Other opamps won't sound significantly different, and may require more bypassing.
The only stage I would consider changing is the master output: that last amp before the Master Out can be asked to run at higher level than the 4559 can handle with ease. Of course if you are not using the master output, that is moot.
