I'd hate to be the naysayer (I'm not trolling, I swear), but this is an awful lot of detail and work to go through for a player base of LordsAndLadies players whose main interest (as it usually is on all of their games) is to find and maintain TS.
Sure, you might capture 3-5 players who are really into the theme and space combat, but dozens of LaL games have shown that the plot falls by the wayside in favor of TS, safe (non character threatening) roleplay usually involving romance, and a metric fuuuuuuckton of ball/coffee/tea/nightclub scenes.
You can come up with an amazing idea, systems, theme, combat, maybe even a new codebase, but at the end of the day, the MU community rarely changes. Every new game will draw in the same crowd (plus or minus the people who decide they can't join the game because of some ancient feud against a staffer or another player) to take a peek. The LaL frequent flyers that are on every other LaL game will come to take a peek, and their characters will fall under the same boundaries of behavior that they partook in on their other two-dozen LaL characters: To seek and maintain TS, safe roleplay, and a metric fuuuuuuuckton of nightclub/tea/ball/banquet scenes.
You're better off using an already existing codebase (FS3), speed-creating a wiki, and hoping that whatever detail you've put into the theme enraptures at least ten people enough to participate in the core metallic while your 20+ other players continue to do the same shit they do on every other LaL game.
In short? Don't overdo it. It's not worth the effort given the shelf life of most MUs nowadays.
