I've never made sausage from bear, but I have from elk & deer. Since that meat's very lean, I always add some beef or pork fat, and that combo turns out very good. Not sure how bear & deer/elk would taste so you might want to try a very small batch.
This past summer I experimented with adding ground turkey to elk (for meatloaf) - needless to say it tasted terrible. So if you experiment, just do a little, or you might end up wasting the meat if it tastes nasty.
