When using an Altec horn atop a direct radiator, you'll want some padding of the horns. The attenuator will serve double-duty as the damper circuit and can provide top-octave compensation as well. I'd put a standard Zobel on the midwoofer. Other than that, the second-order network you've described will work just fine if you cross-connect the tweeter, wiring "+" to "-". The tweeter motor and the woofer motor should be aligned vertically, within four inches front to back. That gives you a pretty wide position tolerance window where performance will be good.
