The other end of that is that the Firestarter for instance would need to have an absolutely ridiculous number of hardpoints (2 Ballistic, 6 Energy, 6 Support) to jive with this system if I'm correctly understanding the way you're postulating it.
That would be a natural consequence, yes. Basically to the limit of what the MWO hardpoints allow, before you start 'cutting corners' like thinking that MG rounds are coming out of the smaller hole in the laser box.
