The time alignment is mostly due to the reactive impedance of the inductor. It is possible that in impedance compensation circuits that it could make a difference but only if the coil resistance is needed. Coil resistance can easily be changed with the gauge the coil is wound in.
A very simple fix all around would be to measure the resistance of the cored coil and get enough larger gauge air core coil to have the same resistance as the original iron core coil. Overall results would then be improved over the original design, but more costly.
I recommend that if all possible to use an air coil at least on the tweeter.
