I am wanting to mod the Vasari Kortul/Devastator in such a way that it fires light beams(similiar or virtually the same as the titan light beams that can target SC) from the same hardpoints it fires its regular beam weapons.  Generally, I need to know if it is possible to add a new weapon to the mesh and "share" existing hardpoint locations and if it has any reasonable expectation of working.  End result is that I would like it to use the light beams vs SC while still able to use its normal beams against regular ships.

8 hardpoints, 2 forward firing, 6 side firing (3 left and 3 right).  Just from seeing the Kortul in action, I know that the forward-most side firing and forward firing beams originate very close to one another on each respective side.  Now, unless I am terribly mistaken and this is more complicated than it seems even at this point, it appears to me just from looking at the position info, that points 5/8 and 2/6 are the "shared" hardpoints from a visual standpoint in the game.  This makes points 1, 3, 4, 7 the mid and aft side firing hardpoints for sure and all that remains is to determine which of the 2 of those pairs are the remaining side firing hardpoints (stop me at any time if I am mistaken).  Again, logically based off the position info, the remaining side firing hardpoints are either 8/6 or 5/2.  From my research I believe that the models are aligned on the y axis (top down or some such) but without a graph calc handy to try the different points I can't figure that part out in my head as to which is it.  Worst case scenario, I pick one set and will soon find out if I am wrong, assuming I even make it that far.  Now, my idea for this to work is to add 6 more points using the same Position/Orientation info as the 6 current Side Firing hardpoints and naming them "Weapon-3" in the mesh.  Once that is done I can edit the Entity file for the Kortul with the new weapon info and stats.  Now, the $4.05 question is, will this work?  If everything so far is feasible, is there any way to set a weapon to ONLY attack SC?  Any way of making it so it cannot be used if the normal beam weapons are in use/actively engaging a target (frigate, capship etc) since they are sharing the hardpoints...  Thanks in advance to any advice on this matter.
