This is one of, if not The, slickest energy weapon packs out at the moment. Especially now that it is on weaponcore.
Here are some suggestions on things I think would enhance and flesh out this pack to make it the go-to pack for adding energy weapons to SE.

Large Grid -

- Visual pass on fixed laser, or adding larger laser, with new model that is styled in the same manner as the barrels of the turrets. This could expand options to blaster, pulse laser and beam laser types.

- New weapon class - Blaster - that uses barrel geometry from the small grid turret. This would be the energy projectile type that pulse lasers have in first WC version of this pack. this would mean returning pulse lasers to the very short duration laser beams of the non WC pack.
--Personally, I'd like to see the blaster being a hybrid ballistic/energy weapon that draws hydrogen as ammo, but is less power hungry than a pure energy weapon.

- Bringing back the pulse laser as a true laser. Obviously, this would mean different colours for the pulse laser and blaster. Green bolts look really good, but should probably stay low-caliber only. Cyan bolts currently look a little flat, but this could change. Perhaps pulse lasers could have an indigo/royal blue hue? Or perhaps blasters could have a lime green or chartreuse colour?
--These could be like an energy railgun, high penetration, low splash.

- Twin-barrelled mid size turrets, and maybe a compact 1x1 footprint AA quad blaster gun, much like the ballistic telion AA. the trade-off being a deeper, 1 block deep base.
Small grid green bolts would look really good for this weapon type.

- Replacing reload mechanics with overheat mechanics that are more dynamic. It feels weird to have an energy weapon fire 6 out of it's 8 stored shots, then when firing the next burst, firing2, then having to reload before firing the rest of the burst.

Small Grid -

- Reclassifying the small grid turret as a blaster. Ditching the reload after x number of shots for an overheat mechanic.

- Larger 5x5 twin gun blaster turret, that is essentially a stripped down version of the large grid AA turret suggested above. Maybe even the quad, with the full 5x5x5 internal structure as a consequence for that much dakka.

- Fixed blaster, roughly the size of gatling

- Fixed laser and blaster guns of same power output as the 1-barrel turrets from large grid. 3x3x10 size? Could be a rescale of large grid ver.

- 1x3x3 PD laser for small grid

Other suggestions -

- For both grid sizes - Interior blaster or low power pulse laser.

- Built in emissive/beam/projectile colour controls. Allowing players to set their own colours could allow for more "cinematic" battles using this pack.

- Multibarrel beam lasers fading or switching beam from one barrel to the next to maintain constant beam output. Otherwise, why not just build a single larger beam emitter?

- Have lasers act as light sources, at least when firing.

- Perhaps give lasers the thruster flame effect? this could act as an idle glow and a muzzle flash. Not particularly realistic, but very cool. This could also apply to railguns, similar the the depiction of railguns in the Expanse TV series.

- I REALLY want to suggest energy missiles. 0% realistic, but potentially cool to unload a swarm of neon bolts, weaving toward a target leaving glowing trails through space. So, plasma swarmer? Launcher could be similar to swarm missiles, but with a honeycomb of the glowing "eye" from PD laser and current fixed laser in place of missiles. Fires plasma fireballs like the blaster weapons, but these ones home in on target.
