I updated the OP with a new weight gain sheet for the half kaizer sprites. I changed to imgur for hosting as suggested, and otherwise I'll keep posting in hopes that people will be inspired to use my resources or even share their own. Also in order to actually 'outfit' the template, here's the process I went through:
1. I googled halfkaizer sprites to find as many resources as possible.
2. For the 'thin' character, I mostly try to use finished sprite assets, as to save myself time and effort. Besides, it's a lot easier to modify something to look right, than to create it from scratch.
3. Make sure to use a program that supports transparency and layers, like photoshop or the free gimp, and just move clothes over to the fatter versions of the character, and adjust the sprites as needed.
If you're going the minimalistic route, you can outfit only the still standing sprites for a character that won't be walking around. Or you can even change the sprite for just a single facing, for a character that won't move, or turn around when spoken to.
EDIT: Short disclaimer. I'm a horrible artist, and a complete beginner to spriting. It's very likely that indeed anyone could do better than what I did. So keep that in mind if you find any of the sprites I made to look 'goofy', or if you're afraid to give it a shot yourself.
