The only suggestion I would offer is that two are on one leg. And that if possible have two outlets that will be closest to each other originate from opposite legs at the breaker box. This will help in case you have some grounding issues in the future you can easily try another leg. If installing new outlet boxes and not re-using existing outlets, I see no issue in having two or all three in a single box. I don't see how they would cause any interaction with each other but if you do have two in one box try to use a left and right leg together in one box for convenience.
