Then don't do it. Its a terrible strain if the place doesn't seem to be fixing what you need help with. You can come to resent it and then want to move the child another time. Multiple moves can be stressful in themselves.
I would keep the kids at the same school - they will see each other around and that kind of sibling support is worth a lot.
For what its worth, I had two kids in different schools (one private, one public) and it didn't work for us at all. Financially, logistically, and academically. The public school eduction was so much better than the one we were paying a fortune for and the public teachers so much more amenable and easy to communicate with.
We swapped our private kid out to the same public as the sibling and they are both very happy and doing well. There is a lot to be said for familial support.
