Out of all the azumanga girls, Yomi would be the easiest to find in real life. Find a good high school; girls in low-income area high schools are either already knocked up, or have STDs, or are black. Keep on the lookout for families from the upper middle class; they need to be able to splurge a bit on food to give her those five vanity pounds. She'd be in some sort of academic club or group, so libraries or museums would be a good place to find her, too. Glasses and long straight brown hair? Also not a problem. Only problem would be matching the personality, you'll just have to be very observant about how she acts. But yeah, you could probably find her. Actually, I know a girl who if she were a little less german, and a little more shy, and wore glasses, would be pretty close to Yomi.
