At 10U, I agree the kids will be happy since they're playing other positions, too. If you have parents want to hissy quit because Suzy only pitched 14% of the innings, better off without them now than putting up with their crap for years.Unfortunately, you'll lose a few of them. No matter what you do with a rotation or however you decide to handle circle time, one or two of the parents will feel their daughter is being slighted for innings. They will leave for another team. It's the nature of the beast.
