Good luck lifting 6 tons with a hot air balloon. (That's what this contraption weighs). Even a small one would be out. A four person hot air balloon can lift about 1 ton max, including all the gear, gas, burners etc. That leaves very little room for deadweight such as water, on the plus side you wouldn't have to take any ballast at all.

How about 6 balloons then?

I've seen that movie.
