I would be careful with that though. The 'older' kid who plays right before her might feel self conscious. I have an 8 year old girl doing Grade 7 RCM, and I put her between two 10-11 year old kids doing Grade 4 and 6. Also, if you have an adult who just started, they might feel silly playing in between two 7 year olds. I've only done three recital so far, but I try to account for age and level.
