Seeing as I still have some sets left and because the six crew exactly matches the number of Pistoliers heads I have left, my Mk II Ventrillian force is receiving a pair of Malleus rocket launchers.

 Something I may look at is creating some additional pieces using the weapons mount for the Malleus launchers with a pair of lascannon mounted instead.  Some form of Tarantula or Sabre platfoem maybe?
