Martha Stewart had a school themed wedding in an issue of her Weddings mag. There were custom invitations that looked like retro attendance "roll" sheets, a "test" about the couple the guests filled out with no. 2 pencils of course and apple place cards. The guests took pics by and wrote on a huge flippy style chalkboard. I don't know if you could use any of those ideas, but it looked pretty cool.
I think it's great that you are going for a theme you love. My advice is to choose HSM colors and let the ceremony be elegant. Save the fun, cool details for the reception.
Maybe you could make a wedding logo that like HSM logo has those lights but instead of HSM use YOUR monogram? Maybe that would make a cool cake topper , too? Maybe make that "light" logo your theme? You could use that light style monogram on sooo many things!
