Thinking back on this, I really liked the blade shape (profile, belly depth and length) of the Yard Keeper CG. If memory serves, it could be a little thinner for our purposes here though.
If Dan could start with the YKCG blade, thin it out a little, and add an ergonomic skelly grip (base option, plastic dipped added cost and RES-C handle as top of the line) - I think we'd be there.
I got myself a Yardkeeper CG, by your recommendation, about a year and a half ago, and it is one of my favorite blades. So I am certain a bladeprofile similar to that would work perfectly.
