Uneven bridal party

Little story: We are having a pretty small destination wedding, and initially I had plan to not have bridemaids or groomsman, only my MOH (which is my childhood bestfriend) and BM (fiancee's middle brother), but my only two sister's complained not to be part of the bridal party, so I decided for them to be my bridesmaid and walk alone. But then my fiancee said he feels bad cause then he will like to include his younger brother, since his middle brother is the BM (they are 3 brothers only) if it was ok with me. And I was like of course, I mean am not gonna say no (and I also know I want them all together for the getting ready shoot since they're all mens with their dad). He knew I felt weird about the arragement of an uneven BP, but I said is ok I can put my oldest son (which is my fiancce's step son and is 16y, taller than me lol) to walk with one of my sister, that way with dont have one bridesmaid walking alone, but to my surprise my son told that he knew how I always dreamed about this day, and he wanted to have the honor to walk me down the aisle along with my father (ok! My heart melted complety and of course I said yes). So now I am here with one BM-MOH, and possible 1 Groomsman, and two bridemaids. How can they walk down the aisle that wont look weird? Or should I skip adding my other brother in law as a groomsman? Is it weird to have an uneven BP?


Also! Is it weird once the bridal party walk down the aisle to sit, and only us two stay stading up with the officiant? (The place for the ceremony is on a beautiful yet kind small cliff) I though the BP could sit down and only us stay at the front that way it doesnt look too crowed? Idk. I know is catholic ceremonies inside church the BP sits down sometimes. Idk if it will look weird.
