Weddingbee boards

I really need to finalize my wedding party, but I'm torn. I have 3 sisters and no brothers. I have four close female friends that I'd really like to include.  My FH wants to have his sister as his "best man," and then he has two other GM (including his dad and a guy friend). He has some additional guys he could ask, but I think he feels a little like it'd be level jumping on their friendships. He doesn't have any brothers. 

That leaves us with 7 BM on my side and a Best Woman and two GM on his side. Also, I'd really like my nephew to be ringbearer-- I don't know where he goes, but he's really young so positioning him near his mom seems smart. We talked about him having my BIL (conveniently, the nephew's father) but again that would be kind of just to add people and not because he really felt close to him.

I'm not big into tradition or this-has-to-be-this-way in the least. But that's really unbalanced. I've thought about giving the friends readings to do instead (the standard suggestion) and one will do a musical performance. But they've been my good friends for a really long time, and the idea of them not being my bridesmaids kind of makes me sad. Plus one of them has public speaking anxiety, and I can't think of anything that she could do that doesn't involve talking in front of crowds (other than the guest book, but come on, that's totally lame). I don't think I can do some of these 4 friends and not others-- that would cause hurt feelings. We're having around 100 guests, so that's the other part of it-- is 7 just too big of a wedding party? I never thought I'd have such a big wedding party-- I'm not a big wedding party kind of girl-- but with 3 sisters it really adds up. 

My fiance has some female cousins whom he is close to, but while he likes the idea of having his sister as his best man, he thinks it'd be weird to have more than one woman as his attendants. Thoughts? Has anyone been to any non-traditional weddings where the ceremony line-up didn't emphasize symmetry so much?? I am all about doing things differently.

It drives me crazy that the traditional wedding line-up assumes that the bride only has female friends and the groom only has male friends

Thanks for the feedback, everyone. I appreciate everyone's thoughts.

It's becoming clear that what I want is to have the 7 BMs, and that I care very little about symmetry. BUT my fiance seems to think that it'll make him look bad, having so many fewer GMs than BMs-- like he didn't have enough friends to ask or something. Would anyone actually notice/ read that much into it/ draw that conclusion? I don't want to do anything that makes him feel uncomfortable on our big day, nor do I want him to feel pressured into asking people he doesn't actually want up there?

Thanks for the suggestion on the ringbearer. I actually talked to my sister (his mom) the other day, and she said the same thing-- that there was no way he was going to stand still for anywhere near long enough. :) Oh well, he'll look cute walking (or being carried) down the aisle.
