Fat Pants crisis

Having real difficulty making this puppet, his character design makes him short and fat, but the armature is designed for a tall, slender character. I'm not going to modify the armature, that would take too much time, and it would be irreversible. I will have to add more bulk to the legs and 'gunt' to make it even, this will make him him a lot heavier than originally planned, which will almost definitely make him harder to animate, but i'll decide what to do about that when he's finished.
I've been sculpting, destroying, and re-sculpting this fat guy for over 10 hours now, and it's one of the most difficult puppets i have ever tried to make, i love it.
