It might raise them by one tier.
Maybe some of the homebrew disciplines could be picked- like archery for rangers.
Monk: Setting Sun
Fighter: Iron Heart
Ranger: Tiger Claw or homebrew archery one
Rogue: Shadow Hand
Barbarian: Stone Dragon
Paladin: Devoted Spirit
Marshal: White Raven
These would be starting points. Though personally I'd give them full manuever progression, and drop the ToB classes. If I wanted to "ToB-ify" the core classes, and have no ToB classes around to overshadow them.
