That's basically PF2 (which is also largely by the same designers), except that PF2 is much less tactical, and where 4E has a whole role dedicated to crowd control, PF2 doesn't have CC abilities. I'd say that PF2 is more balanced but less streamlined than 4E.
And to be fair, that wouldn't have much appeal either to non-4E fans.But there's also a temptation to say "I like the AEDU power structure and healing surges and tight math, but the existing powers are too narrowly focused" and try to create something more like "classic" D&D. Which would be an interesting exercise in game design, but wouldn't have much appeal to existing 4e fans.
