Let's see, you could add a few items that don't take up much space, such as sewing needles, a thin signal mirror, a few tinder tabs, safety pins, maybe a small mag bar instead of the matches, using the Micra as a scraper. I don't see a container for water, maybe an oven bag could be used. Add some dental floss for cordage. Aluminum foil for a pot. I like to include multi-use items in my kits.
