Hello, I’m planning on participating in the OUYA game jam thats running simultaneously with this one. Would it be acceptable to make one game following both jams rules and submit to both?

I would normally say that's fine. But if you're planning on developing for the OUYA the judges for this jam are going to have a hard time playing your game. You're welcome to try, but I'd recommend planning a build for pc as well as whatever you do for the OUYA
