Sorry to be a downer, but I'm not convinced that a missile spam based mod would be interesting in the Starfarer engine. There are so many things Starfarer lacks that are integral to the dynamics of Honorverse ship combat; electronic warfare, stealth systems, the way shields (not to mention wedges!) work in the setting, the way Starfarer ships don't exactly have formation-keeping as a high priority and most of all, that there's very little in the way of player control over missiles, so the mod gameplay would almost certainly boil down to clicking the missile fire button as fast as the cooldowns allow for and hoping you get luckier than the opponent.
A sim or tactics game would be a much better platform for it, I think.
