The whole point of having a crossover is to divide the task of full-range sound between the drivers.
If you have the mid-range drivers running the high freqs, and the woofer running full range signal, you'll undoubtedly encounter comb-filtering and other undesirable audio artifacts.
Now, if you built TWO of these, you do a A/B test with one cab wired as you described, and the other cab wired with the conventional crossover configuration.
Then, when you discover that the conventional configuration actually sounds better, its a simple task to re-wire the "test" cab to the proper configuration.
