It doesn't really cover enterprise patterns or refactoring in any depth, so I'm not sure why you'd replace Fowler. I agree skipping uncle bob is probably healthy for everyone though.
It has one chapter that sumarizes refactorings.
Enterprise patterns or design patterns in general are about software design. IMHO design patters are the worst way to learn about design in software.
The fowler book on design patterns isn't really like gang of four or whatever - it's more descriptive of the different approaches you will really find in enterprise software vs. a bunch of fancy OO madness that turns junior engineers into architecture astronauts.
