help with adding missile turrets... any ideas?

[gruntmaster1]

So in order to give the game weapons a little more diversity I have been trying to implement missile turrets which have proved to be more of a headache then i originally thought -_-.

First I thought it would just be adding a new xlm schema though you can probably figure out how that went. Currently the only option seem to be adding a missilemodule with ONLY_BigShip as the attachment, but i wanted to hear if there are other possibilities and how to replace a turret with a missile slot?
