I like the idea of incorporating as much personal meaning into the ceremony and reception as possible. If your GLO and its symbolism are meaningful to you, why wouldn't you incorporate it? I chose hymns to be played before the ceremony on the basis of what was meaningful to me - so while some in the congregation were probably going "The Saints of God? That's not wedding music!" the important thing is what it meant to me.
So too with colors - you can just pick colors that are pretty, but isn't it nice to be able to pick some that also have meaning? I'm well-versed in the Victorian language of flowers, and chose flowers for my bouquets according to what they meant - but also included the white rose of Sigma Chi and the pink carnations of Gamma Phi because of their meaning. Cheesy? No - it could be done in a tacky fashion, I guess - just like everything else in a wedding. But it can also be done in a very tasteful manner. Borrowing the plywood giant letters of your GLO to be displayed on the church grounds - throwing hand signs at the altar - tacky. Pinning your badge to a ribbon on your bouquet, carrying a handkerchief given to you by your big sister with your letters on it, having specific, meaningful Bible verses in the service, a groom's cake in the shape of his badge, singing a traditional song at the reception - all, IMHO, very nice.
