I think you might have a problem getting an even colour tone.
It's very hard to get a HiLite absolutely even all over, including with the best lighting. That doesn't matter much with pure white as so long as everything is over-exposed, it looks perfectly even despite the fact that there are actually hot-spots here and there, especially if you want to cover a large area.
I think you would get better results gelling flashes on a regular white paper background which, if you've got the sapce and have two identical flash guns firing across the background from either side at an identical distance and angle, can give very even coverage.
The main advanatge of the HiLight is that it gives good results in a very compact area because you can put the light stands virtually inside them, and the subject can be positioned right up against it if necessary.
