To follow-up...I did it and it sounds great. I gained a bit more clean headroom and a fuller bottom end. I think it works better with pedals and the sound has a charm all it's own. I lost the traditional "quacky" character that I could pull from the little 8 inch speaker and smaller cab, and I miss that a little. I've moved the chassis back and forth a couple times and I have decided to keep it in the bigger cab. And it looks great too.
