Lasers that leave a Dragonslave-esque explosion sphere upon impact (or proximity/time-fused, like Hayate's Hræsvelgr!) with anti-ship and anti-air variants.
Uhh...more wings!
Uhh...Galactic Cyrvan-Terran-Codori Alliance co-operation...LSF developing missiles with energy warheads to fight off Nordera ships. If not plausible fluff-wise, maybe scaled-down nuclear missiles for fighter use.
A zoom thingy for sniper-ish weapons (like the railguns).
Missile pods, launching lots of heatseeking swarm micro missiles. AND PURGED WITH EXPLOSIVE EFFECTS!
A subspace transmitter capable of calling in LSF Nanoha.
Nanoha's Blaster Bit system on an LSF ship to make a Blaster-3 Divine Buster!
Rear-facing missile pods, launching swarm heatseeking missiles backwards.
More suggestive loading screens like pantsu from M24!
Can't remember what else...
