Just an idea I had for a mount for Devnull, Adamant, or whatever mods anyone is working on... probably suggested already but I haven't seen too many mods using it
Gatling Mount - Extremely miniaturized Version of a weapon, typically used in large batteries for a "machine gun" effect. Each shot does a large (for the gun's size, not overall) amount of damage but has a low chance of hitting; however, the large number of shots fired ensure that at least a few will hit.

Direct fire only
I also had the idea a while back of having a different Spinal Mount for each hull size (sort of the weapon equivalent of engine/armor/cloak scale mounts), each of which has the same to-hit penalty but increasing efficiency in terms of damage/kT. Of course the question would be "why can't you put a destroyer spinal weapon onto a battleship and give it a smaller penalty since the battleship can support the actuators to aim the weapon?" and it would just degrade into the existing mount system only with to-hit penalties... also, the whole idea of nullifying the to-hit penalties of gatling and spinal weapons with COMBAT SENSORS is kind of ridiculous anyway... "yes sir, our sensors are so good they can actually turn our ship in another direction / make our bullets spray out in a straight line!"
