Very uneven BP- Need honest Opinions

Please tell me if you think this is going to seem really weird to people.

My BP will consist of my two sisters. One will be my MOH, the other will be a BM.

FH has this bunch of guys lined up:

Best Man- Brother
RB- nephew
GM- nephew
GM-friend
GM-friend
GM-friend

What do you think? Are our pictures going to look really off-balance?

Anyone have any suggestions as to how they can all walk in to the ceremony or reception? It is even too many guys to let 2 of them walk in each girl. I don't want to ask him to bump out any of his GM, and I really don't want to add anyone to my BP.

Thoughts?

How old are they?

You can have the Best Man and a GM walk your MOH down, two GMs to your BM and then the one GM and the RB together?

Edited to add, if one GM is younger, then he can walk the RB down, is what I meant by asking how old they were. I hope I'm making sense!

Here's mine...

MOH - Godmother/Cousin
BM - FSIL
FG - Bride's Niece

BM - FBIL
GM - Brother
GM - My Best Friend
Jr. GM - Groom Nephew
Jr. GM - Bride Nephew
RB - Groom Nephew

I honestly...could care less about it being even...the people who are important to us are in our wedding. I wouldn't omit people or get 'fill-ins' to make it look balanced. JMHO.
