I'm still a fairly consistent Planetside2 player, so I have to say that I'm all for this, but my perception may be a bit skewed. That being said, the alternative to playing in the regular servers is to hold a "server smash".

I've played in a couple of these and they're a ton of fun. The main thing is that it's logistical nightmare and you really do need a devoted person organizing each faction, and platoon leaders under them to make it manageable. Not to play in an organized fashion like in the server smash matches, but to play it get the keys out to people and organize the match, as I imagine this would be fairly relaxed. The main thing is to get into contact with the guys in charge with serversmash and see if they'd be open to the idea.
The bonus to using the serversmash server is that each character is fully unlocked, so there isn't any equipment or gun that the player doesn't have access to. The serversmash server supports around 1000 people (333ish per faction).
I'd look into it. But I don't organize them, just play in them.
