I'm going to say that trying to get a turret to work in the time you have is just not a feasible idea. Not because the mehcanical side of it won't work. You already have most of the hardware present and 12 hours is enough. My team went through 4-6 major drivetrain overhauls this year depending on how you count them. We did it and never missed a qualification match and only a couple practice rounds. However in constantly changing our drivetrain we screwed up one very important part of this game, programming. Nothing was ever settled and the programmers had to constantly tweak gains and alter programs to make sure their old code still worked. In the end even though we had at various points a working camera we ended up just going for 10 balls in the corner because the code broke and we didn't have the time to fix it.
So what i'm trying to say is, i'm all for physical modification but be careful. If you have 12 hours plan to do at most 3-4 hours of modification so that the rest of the pieces can fall into place. Drivers need practice and the programmers need to code. The faster drivetrain will be useless if the drivers can't control it and that turret won't be useful unless its pointing at the green light.
Thats all from me.
