You pretty much have no chance of being 6ft or less and fighting heavyweight irregardless of muscle mass because there is going to be someone else with a decent amount of muscle mass that is 4+ inches taller than you. A very few people can pull it off (Mike Tyson) but the odds just aren't in your favor.
Heavyweight should be 220lb or so and up, light heavyweight 200-220 lbs and work your way down from there. Light heavyweight would be a mix of taller/moderately built fighters and short built fighters. Heavyweight can be all the 6'3''+ 250+lbers.
