If any of this goes through, you're going to get a lot of people whining, and rightfully so. Some of the factions you're mentioning already have pretty superior equipment - Kusari's ridiculously fast fighters, for instance, or Rheinland's well-matched pair of bombers.
When we get into this, I might come and ask something like this: "Well, yeah, these are powerful factions, but why am I gimped because of that? I want a more powerful XYZ for the XYZs!" I mean, think about it. Take the Hackers, for example. People talk about how lawfuls get ganked in Liberty, but having been on both sides of the law in Liberty quite a bit, I've found, personally, that unlawfuls get ganked much more often, and - more importantly - by much bigger ships. The Rogues have the Barghest, yeah, but they won't share, and the Broadsword is almost as easy a target as the Upholder. Why shouldn't we get our own SNAC? Maybe one that takes less energy to make up for the Broadsword's small plant, or one that does as much shield damage as hull damage.
Or think about it this way. The Phantoms have their own, slightly superior weapons, right? Sure, they get help from some huge alien empire, and really, out of RP, they get ganked a ton. But doesn't the same sort of thing apply to the Hackers? After all, all the Phantoms really get are a couple bits of leavings, while the Hackers are made up almost exclusively people who worked with technology for a living for years. And we get ganked too, quite a bit, and there are more of us to be affected by gankage. So shouldn't we get something special?
Now, I am not saying the Hackers deserve something cool and unusual in particular, I'm just using them as an example. The moment you add "special" weapons for multiple factions, everyone is going to want them. It's an extremely slippery slope. Even if everyone gets something, there's going to be constant bickering over the exact balance of all the "uniques", much like there is now about everything from bases to class 4 guns to battleships.
Not that this shouldn't be done, of course. Just something to keep in mind.
