The way I'd do it - and I'm not for a moment suggesting that this would be the optimal solution - would be to have it as a series of interconnected vignettes with the various guests leading up to the ceremony, a la what you did with First Dates & Firefights (which I still maintain is a Fall Out Boy B-side waiting to happen). It'd give a nice sense of continuity and overarching scope; all these people are still living their own lives, but the true power comes from them banding together in celebration of love. It's central to the UF-verse's message that the future is bright and hopeful and, more to the point, deserves light and hope.

Feel free to dismiss these as the rantings of a madwoman, but I thought I'd give you my ideas. =]
