Lilacs for wedding flower/theme

Has anyone used or thought to use lilacs as their wedding flower/theme. They are a very meaningful flower to me, but I am coming to find that they may not be the ideal wedding flowers. I have spoken to a couple florist who wont even work with them. Other than the fact that they are spuratic on when they might bloom, they dont last long. So, I get that they couldn't be guaranteed (Trust me, I have two back up plans lol) but in the event that they ARE in bloom when I get married, I wonder how well they would work. I have heard that they wilt quickly after they cut, but I can just stick them in those little water tubes for my bouquet. Thoughts?
