The idea is clever, 4ed use it right from the start.
Using the same frame for different class and make spells, powers, exploits equals in power level.
The OP present the Warrior, but the same process can be applied to Rogue, paladin, Ranger, monk.
And we can redo the same work using the Warlock frame to add more diversity.
it will produce balanced classes, as 4ed was balanced.
The draw back is the feeling of sameness, but if classes balance is a major concern that could help solve it.
