How to Remember my Father on my Wedding Day?

My father died in May of 2010, my wedding falls one day shy of the anniversary of his passing (I did not think about it when booking the venue). I've been thinking for years on how I would want to remember him at my wedding, and what I would do. I've heard people say that "your wedding day is not a day to memorialize their death" and I understand that. I'm planning to have a seat saved, a bouquet of our favorite flowers made, a candle, and a picture of he and I together. To some it might sound like enough, a lot even, but somehow I'm still not satisfied. I can't have him there in person, but I want to feel like he's there somehow. I'm being walked by someone else, dancing with someone else, and taking pictures without him. I'm 7 months out and somehow I can already feel his absence. I just don't know what to do. I've thrown around the idea of recording a message for him to play before the father daughter dance (I'm dancing with his father, my grandfather) but that might be going too far. I always feel really silly and over the top. Any advice would be appreciated.
