Several of the PP weapons would really shine with multiple sizes.
Enforcer Cannon S2 = The bridge between C2 Multicannon and C3 Cannon
Enforcer Cannon S3 = The equivalent of S3 Multicannon but more fun
Pack Launccher S1 = The "Macross" launcher for our Eagles and Sidewinders. Also, would be hilarious and see an Anaconda firing 8 of those. Deathblossom indeed.
Pacifier S1 & S2 = Why not? Tighter spread and lower damage but still suck due to the EXTREMELY limited ammunition.
HUGE mining Lance = Really, why not. It's not as if miners will become the PVP lords of Elite...
Imperial Hammer S1 = Well, what would make it imbalanced really? It's not like the S2 is the gift from the gods that makes the regular railgun weep.

C4 weapons need more love..all we have are Plasmas and Cannons.
-C4 Cluster Mine Launcher [Drops 6 mines behind the ship]
-C4 Anti-Cap Ship Railgun [give it double charge up time but ginormous damage]
-C4 Pulse Laser [Drains WEP capacitor with one pulse]
