Have had the balls to carry on and move up to heavy to fight louis?

Anythink???

I doubt it. The main reason why Armstrong held 3 titles at the same time was so he could make a lot of money and be just as famous as Louis becuase Louis was stealing his fame.

Had the balls? That fight would be suicide. Armstrong was basically a natural welterweight. The middleweight title may have been within his reach but LHW and HW would be far too much.
