Sounds heavy. Try using minimal materials for holding the lights in place then using white foamcore for the walls. I had decent luck building one that attaches to my strobes, I built mine to be around 30" x 40". I used a 2 dollar translucent shower curtain and some velcro for the diffusion material. Double diffusion seemed to help with keeping the light even.
You might want to run a test to see what F stops you'll be able to get just by puttng diffusion material in front of those fixtures. You might be suprised at how little light you actually get out. If the F-stops look ok, then go for it!
How were you planning on standing it? Just directly on the floor? That will limit you to some degree as to what styles of lighting you can do.
