What a horrible idea.
Yes, I admit that Elite as a PvP game is broken: it does not encourage consensual and/or meaningful PvP, while not discouraging anti-social and non-consensual PvP enough, either. End result: most PvP is gankers ganging up on non-combatants, or PvP players arranging outside of the game to meet and fight.
But to have two completely separated player communities would not work, either. The Galaxy is huge, and outside of the few player hot spots you barely ever meet someone - especially if you further splinter the player base. I would hope for the opposite: cross-play between platforms.
There are lots of ways to fix the "PvP problem", and good solutions can be found right on these forums. Why FD chooses to sit on their hands wrt. PvP, I simply can't understand. But I still hope they'll eventually understand that the PvP game mechanics, risks and rewards need a complete overhaul.
