seperating the 2 plants is gonna severly damage both root systems, but having them in the same pot is also a very bad idea. I know your most likely going to want to keep them really bad, while i would not spend anymore time on them and start over, so taking that into account I think you might be best off leaving them together(in as big of container as u can find) and start flowering soon. root systems grow much bigger and faster than you would think(at least thats a mistake i made when i was new, lol) at first, seperating them would be a nightmare.
