If I played the NR more, its very possible that I would disagree with you entirely as from my current experience, I've found that they rely heavily on maintaining fighter superiority and relying on their bombers for damage rather than direct ship to ship combat, thus meaning that these different missiles would make their ships basically good at everything making the faction itself vastly overpowered. I can't say that with full confidence though so I didn't. What I do know is that after countless hours playing the imperial factions, I understand that the last thing they need is another ship to ship weapon cause reasons. So I'm responding to your post where you said
Victory SD I depends on which faction. If the lineups have some ships with good antistarfighter armament beside VSD, she could get the Assault Concussion (20 pulses instead of 72). And maybe for Crimson Command type Victory Destroyer, Crimson Command fluff doesn't indicate which Mark of VSD is used so if you go with VSDI you can swap out her missile loadout as indicated in the previous sentence.
Because you seem to want to make changes that aren't really needed. And even then, I only commented on the crimson because I don't speak for the team, but changing the hardpoints sounds like unnecessary extra work.
