I like the idea, but I don't get it I guess.
Now the top can't be removed? If it's a trailer queen, pull the top and save a bunch of weight by not having such a huge cage surrounding the top. Also, if it's a wheeler, why worry about the body that much? Once again, seems like you could save a bunch of weight by not covering all the body pieces seeing as most of it is just cosmetic.
Granted, it looks pretty decent, but seems like it's a bit of a waste. For a trail only rig, lighter is better.
And your pipe is fine for slow tumbles, but not even close for high speed rolls.
