What scares me about a lot of these ideas about charging for weight is going to turn into a lack of consistency. I weigh 105Kgs, am 6' 0" and wear a 35 jeans. I am not fat, I dont work out. My best mate is the same size as me (shoulder width is a bit less) and he weighs 20kgs less. I dont occupy more than my own seat ever, but I would be seriously penalized by a weight charge.
Personally I think that a proactive way of moving people around as is already the case for the most part is still likley the best way of achieving the most out of the current (and I say terrible) state of seating in aircraft.
