With fs2 open you can get near simultaneous firing of missiles with the expanded corkscrew entry.  

Just give it a miniscule time between missile lanch and set the rotation to zero - I did it with a torpedo mounted on the Neptune from Inferno and it worked beautifully - although only one of the missile banks would fire.

I wish we had a "fire turret/missile" SExp...

In the B5 spinoff series Crusade...the Excalibur had a couple of turrets with a heavy pulse cannon and two medium sized beam cannons all on the same turret.  It looked wicked cool with rapid firing beam weapons and a similarly rapid fire pulse weapon all trained at the same target.
