Think you might find it hard to unite everyone against any common enemy when not even the Sansha pulled that off. For some of us, the Empire/Federation/State/Republic/Guris/Angels/Whatever is a greater enemy than some wooOooOooOOOoOOooo space magic hurrdrones from whereveristan, w-space.
It's the way of the sandbox. You'll never have unity and that's an absolutely fantastic thing because it'd be boring as all fuck.

A big NPSI RP fleet would be fun, but it wont be inclusive to all due to factions loyalties and such.
That said...two big RP fleets gunning for each other...will never happen but if it did...
... oh, don't strike down your hopes just yet. Disclaimer: Don't get them up either. There are very minor ideas aired in very minor circles, that's all.
Anyway Anslo, on the subject of non-engageable. There is a lot of it out there, even if you don't agree with that. Most of it doesn't even come to the attention of people who might engage, due to private channels etc etc. Some of it is not engageable due a simple thing called being IC. An Amarrian Holder burning Blooders alive might be a fun event and all, but it's not exactly something that'd be engageable for a lot of people due to either a distaste for that kind of thing or because their characters would have to do/say things that'd just make it a bloody dramafest and ruin the whole thing.
Same reason I can't have Miz go to the LockStockWhatever place. Some guests there have been known to say/do things that'd flat out
require the removal of their larynx with a shattered whiskey glass, and that's just drama that shouldn't happen.
There are a lot of stumbling blocks to get past for a lot of RP, which makes it unengageable in some cases.
