I'd probably go Rainey and Gray. You say Rainey hasn't impressed when he got opportunities but he only had 2 games with any significant touches. 174 total yards on 22 carries and 3 catches and 111 total yards on 11 carries and 7 catches. He's been good when he got touches and he's projected to get 14ish carries this week so there's a good chance. He's not going to light up the world, but for a double RB bye week he's a good fill in I think.
Gray is a total gamble like you said, but he's got more upside than Stacey and Sims is a total unknown.
