I would be fine with a 6th Edition in a few years, but I think much of what I would change could be covered in a 5.5 Edition.
To start, include all classes that eventually get included in 5th in the 6th Edition PHB. None of this condensing classes down to 4 groups or anything else. I think what 5th edition did with the classes and subclasses works great. State there will be no new classes in the future. I'm hoping this means that the PHB would include classes that will eventually get released, such as the Warlord or Mystic. All future 6th supplements would add subclasses, but not new classes.
You could include most of the current material, just make it more balanced and desirable.
To that end, standardize when classes get a Subclass, preferably all at level 2 or level 3.
Emphasize the subclasses with abilities that really make the subclass stand out versus other subclasses in the class. This should be a good portion of their power.
Make an even number of subclasses for each class. PHB could include 3 or 4 subclasses for each class and be fine. None of this 2 for some and 7 or 8 for others.
I like the ASIs in 5th edition. I like Feats also. I think they should be independent of each other. You still gain an ASI every few levels in a class, but it has to be an ASI. You gain feats at set levels also, but it has to be a feat. Choices and options that give flexibility make characters more unique.
