Possible phaser turrets for Trek ships?

[Publius]

The USS Bozeman (NCC-1941), the sole representative of the Soyuz-class starship from "Cause and Effect", was seen to have a large turreted gun on the extended after section, abaft of where the rollbar would usually on a Miranda-class starship, and two more twin-barrelled turrets where the rollbar would attach to a Miranda-class saucer.

I believe on the original deckplans for the Reliant [the "Avenger" deckplans] or something to that effect, Reliant's rollbar-mounted phasers were called "megaphasers." But FASA and later tech manuals fucked it all up. Too bad, it would have given us some more variety for phasers.
