I help bone out a deer or two every fall. Usually, people start out with their fat, clumsy hunting knives ... and then rapidly switch over to my pail full of second-hand specials: Mora, Henckels, Victorinox, and Old Hickory.
There is a reason why the "butcher" and "green river skinner" blade patterns are universal items. That said, I'm not convinced that pattern is the critical issue.
First, a thin blade is better (simply less resistance). You need a cutter for this job, not a prybar.
Second, as noted by others, a "toothier" edge is actually better for peeling off membrane, chewing around cartilage and bone etc. A blade can indeed be too sharp IMO, both for skinning and for processing. I use a medium diamond or a well-worn garden stone for this type of edge, maintained with a good quality steel (I pick up Henckels steels for a buck or two at garage sales; and I have a Norton garden stone that is now 30 years old and starting to break in rather nicely).
I like the idea of a longish, semi-flexible knife for boning out an animal. There are purpose-built boning knives, but I think you can get a better quality semi-flexible filleting knife for a song and it would work wonderfully.
