Guild Wars 2 Guilds Expanded!!!
Considering that you wont be able to gather your whole guild anywhere or play together, even with a limit of 500, i see little use for a 1000 man guild limit.
New guild features with HoT will allow you to see and participate in both your guilds chat at the same time, so i dont see where your problem is.

Just tell them all to gather in one place, say, oh, I don’t know, your Twitch channel, maybe?, and give your commands there.
As Wanze says, no need to change the game mechanics, as maps won’t support such a large number.
Good luck.
