Hard Tack Variations?

Just pondering, but has anyone heard of hard tack being made from different grains, or variations of hard tack?

My mind immediately went to defatted soy flour. Relatively cheap, not as much as wheat flour obviously but much "denser" in protein, which is very valuable for long hikes or just time away from food/civilization.

I figure maybe also maybe a protein isolate might be just as good. Combined white flour with a protein isolate, and proceed as normal. Cheap, and effective. I do like that soy has fiber though, would be pretty handy in times of need, as other things like TP could be rarer than preferred.

Anyone, has anyone thought of doing something like this?
