While I like this idea, I think that for Veterans to be back they need to:
Remember Disco exists in the first place: Now, that is up to word-of-mouth promo, unless Librelancer is actually completed.
Apparent activity (on the Server/Forums/Discord/Skype Groups): Cyclical issue, if there seems that enough people play, they'll try it out, otherwise they'll go play Steam game #8569.
Changes: Sometimes simpler things that don't require as much work could serve as well. Focusing on appearance/fashion could bring more results (to the point many multiplayer games rely on it). Making alternate models of existing ships with different textures, either as models fabricated inRP by different factions, civilian-ships, or faction/player faction-specific textures. Older (non-import) models could even be kept in-game as either older or alternate ships already in-game. Having more equipment variety (guns, engines, etc) would be a plus.
New players need some easily digestible introduction to Disco, and this is where I believe this guide could be of help. While vets that have been away for years (like me) would certainly benefit from, if the goal is increasing activity, it might be more productive to look for people who haven't experienced Freelancer, taking into account that anyone with a computer can play it (the game runs in any modern-era toaster).
