If I *were* to make a pouch for it inside, could I just sew a canvas flap to the pack itself?


Yes, you can sew a pouch for it if you want. It won't hurt, and if it gives you piece of mind......
You can also make a foam pouch for it...with a couple pieces of foam and some tape. That should protect it. But what is in your pack that would puncture it?

One thing you need to do....fill it up and put it in your pack. Then fill the rest of your pack with your stuff. Then drink all the water. Take it out, refill it, and put it back in the same spot in your full pack. Now, imagine doing that every time you want to fill it up.
