Darth Vader's "Imperial March" for my Wedding aisle walk?

I want my wedding to be fun, it's going to be mostly non traditional and I will be walking without an escort down the aisle. My fiance is a HUGE dork, (I'm even having some of those little RPG soldiers painted up to be storming our wedding cake). I thought I could do the traditional piano as the wedding party goes down the aisle and then have a piano version of Darth Vader's "Imperial March" begin as the doors open and I begin my walk down the aisle. I think it would be a HILARIOUS surprise (and sign LOL) for my soon to be hubby. My mother, of course, is horrified, a few friends liked the idea (but they may have been lying) but I think a piano version would be "weddingy" enough, original and fun. I can't ask my fiance because I want it to be a surprise. So what do you all think?
