Need opinions and suggestions for Jr. Groomsmen.

This is my bridal party right now..

1 MOH
1 BM

5 BM
4 GM
1 Jr. GM

3 FG
1 RB

So.. my question is... the Jr. Groomsmen is going to be 10 by the time we get married. I feel a little weird having him walk one of my BM's who are a good 15 years older then him up and down the aisle.

Are there other thoughts about what i could do with this? I think FH is ok adding another GM if need be.
