OK, now that makes sense.
This is actually a good idea, I should probably fix up some bags like these. My main concern with stuff like this is that you need to actually rotate the stock, or stuff will get stale sitting around unused. Hopefully sitting around unused anyway.
Yes, so why not go camping once in a while use up the stuff up and then replenish your bags. by doing this you will discover things you may want to add. Like insect repellent, toilet paper and so on.
