Front Cover Idea

I've had an idea for the front cover of my digipak. It uses a photographic technique that shows motion blur.

I want to use this effect in the following way:

Two people standing opposite each other in a dimly lit room whilst one of the parties remain still, the other will rock back and forth creating a messy 'cloud' of blur in front of the person remaining still. I think this will be effective as it conveys lyrics in the song that I am using, e.g.

"spin me round again... when busy streets a mess with people would stop to hold their heads heavy"

I think this would work wonderfully if pulled off. I'm confident in my photographic talents that I will be able to pull it off without using Photoshop.
