I also use the mineral oil and beeswax butcher block conditioner and like how it works.

I can not directly answer your question but I can say that I used carrot fiber binder with ground pork loin (very little fat content) and it really improved the moistness of the sausage. When I add water I go by feel of the mixture (just add slowly until it feels right) and have not had any problems. Since it sounds as if you have made venison summer sausage before add water like you did before but if the mixture seems too stiff add water a little at a time until it feels right and you should be ok.

It should work just as well as it does for breakfast sausages since you are not hanging them.
