Who knows? But I doubt the Lakers give it up. The Pacers have zero leverage and no one else wants to risk giving up much for him since he said he is for sure signing in LA and any other team trading for him would be a one year rental.
So it would probably be something like the 28th pick, Clarkson, Nance and perhaps something else. But LA really needs to clear cap space so they'd HAVE to trade away a young player to do so. It will be interesting if they try to trade Russell though as Russell, Randle and George all have the same agent.
