Something New

I need some opinions. Ok well for my quinceanera i am having damas and chambelanes. I was thinking of having 4 little girls and 4 big girls including me as one of the big girls. Then for one of the dances to have like the little girls to dance however they wanted to but the same way. But then for my valse all the girls dance with all the guys and well do you think that it would look weird if you see big girls dancing with little boys and little girls dancing with big guys? i need to know what you guys think and what songs i should use for my fast song. Please help
