You're going to probably want more door control for this 200 point squad. 2 Uggies just isn't sufficient. I recommend getting at least one over-ride unit on the team.
You can start with rodian brutes or trade the Ug Droid Destroyer for an R7. I would probably get rid of UgDD. Since he does not have accurate, he won't kill R2 very easily. If your facing a charging type squad, the squad will have already gotten its use out of R2 by the time the UgDD can make him a legal target. If it's a squad where R2 is towing the shooters around you will likely never get a shot off.
I would just say that most of the time, you'll want an R7 over UgDD when you have 1 point left over. Over-ride is also very helpful when you will likely be out-activating most squads
