This can provide additional bouyancy to prevent sinking, but it will not contribute to stability. The water on the outside of the hull doesn't know what's inside the hull.

I rather doubt that any kayak will be more stable when flooded. If the kayak heels, the water is free to move to a new position. Unless you've got lots of baffling to prevent the water from moving around, you're in trouble. If you've got sufficient baffling, you've got nowhere to sit! I thought we've been over this before? And the conclusion every time is the same: flooding a kayak is a bad thing.
