If you're considering that much lighting for the wedding day then I assume you're working with "at least" one assistant who is only tasked with moving and setting up your lighting?
I've been shooting weddings for more than a decade now and the most complex lighting I've ever setup on a wedding day was two strobes with two 40" shoot-through umbrellas. And those weddings were ones where the bride booked me, a second shooter and an assistant and we had time built into the schedule to move the lights around. Your weddings might be different, but most of the weddings I book are so fast-paced that setting up multiple off-camera lights isn't an option.
Most of my weddings are shot with either bounced on-camera flash (
Neil van Niekirk style) or with a single hot shoe flash and small soft box off camera triggered by PocketWizard and held in position by an assistant (the "light on a stick" method).
Having said all that, I will setup much more complex lighting for studio or location engagement portraits before the wedding day ... it's just that multiple strobes and light modifiers generally aren't something that you can work with on the actual wedding day (even before or after the actual ceremony) if you're crunched for time and space.
