yea the burst wouldn't be a problem, TS just doesn't support more than one turret. you'd have three voxel files
voxel.vxl ; the body
voxeltur.vxl ; the turret
voxelbarl.vxl ; the barrel
then the game automatically puts them together as one unit.
At best, you could make the barrel AND the turret look like turrets, and make the hva so that each one is on each end, though the turret-section would be going up and down, and the fireFLH would make it only able to shoot from one place.
So the only thing would be to put it on CNCVK's ETS wishlist
