nice try, but the problem with projects such as yours it that inevitably aluminum bends or gets tweaked (twisted) even with that top brace, and you will have a hard time maintaining your frontend/rearend angles without some additional bracing.
people did similar mods when the mini't first came out, but they ended up with a spagetti car.
might have been better had you used a medium such as carbon fiber.
the other problem that you'll run into is that the mini-t sized wheels and tires will look puny and way undersized once you mount up the huge 1/16th slash body.
the alloy does look purty all polished up though.
