By the time you built one heavy enough for a 'zuk, you would have almost enough money into it to buy a fixer upper trailer. Buggies weigh less than 1/2 what you Sami does, and you have to account for the extra height you would need to get the tires off the ground (including droop). When you were done you would end up with a even higher center of gravity than your rig already has, balanced on two wheels (like a teeter-totter) and no brakes.
Consider the weight transfer you would get to the back of your tow rig whenever you needed to panic stop. Also, consider the effects of a blowout.
