edit: This might read a bit more scattery then I like, apologies, wrote this up while being up waaay later then I really should be. Hopefully tomorrow I'll be able to type up more coherant replies.
I have quite a few ideas I'd love to present to CCP. However, realistically speaking, the CSM isn't an "idea generator". It's a focus group and consultancy, and I think players expectations have bloated out what Candidates aim for, or promise to try to achieve/look at.
That said, yes I do have ideas. In terms of FacWar, most of mine right now are mechanics in nature. Namely, novice plexes and pirate frigates. Pirate frigates are just far too powerfull to exist in the same space as t1 hulls, as by their nature they bend rules of the game (such as web range/strength, nos, speed for hull size) While t1 hulls can and do beat them, the advantage is certainly with the pirate frigate, and to continue to name what is also arguably the most contested and important plex to hold as "novice" is bad design. I think theres' only two viable solutions. Either create a new plexed named Novice, with a mid range timer (say same timer as a medium), and only t1 hulls allowed, with the current novice plex rebranded. Unfortunatly, as the rest of the plexes are size classed "tiny" isn't appropriate, but something akin to high intensity would nail what it is.
In terms of the alliances, I don't think 4 way is needed. The biggest issue for fac war isn't other militias coming to the warzone you're in so much as the complete lopsided nature of Cal/Gal vs Amarr/Mil. Amarr/Mil, due to the ewar effects of rats (for missions) and possibly the relative value of LP items, is vastly more suited to farming, which dilutes the entire effort made by people who are there for the competition. It's not even about loyalty as much as your activities as a PVP pilot doesn't really matter if the farmer swing is against you. Before we introduce new factions, or change the alliance dynamic, I think a full review of the system is in order, coupled with introducing gradual changes and a proper review system of what's affecting what.
For faction lore, I want to see an end to single faction dominance at any given time. Focus is great for a release, or build up, but especially with the recent drifter release, it was a bit long for us to be saturated with just Amarr focus. More attention for other factions, even on minor details, reactions, or unrelated events, alongside the main arcs would be appreciated. I think these snap shot injections from stuff like Frostline and the Crimson Harvest are a good platform to work on as a breather during heavy plot line events.
I also want to see a bit more outsourcing of live events to players, with the use of vetted ISD volunteers, or similar, able to pick up the slack where CCP might want to do something cool but don't have the manpower. One suggestion on Slack from a player was an idea of a submission system, where CCP can apply what they want to do with a submitted idea, and doll it out to those interested volunteers to cover it.
As for more on pirate factions, I have a few ideas I'm still ironing out, mostly related to missions/rewards, and the potential for the roaming NPC AI. It involves not only expanding/refining PVE content, but also ties in to making New Eden feel more like a living, breathing place, where you can have more chocies in regards to loyalty through your PVE. Watch this space.
