Actually, there's a different criteria for the first four seed lines:
"The first four teams from any conference placed on the top four seed lines must be assigned to different regions (unless five or more teams appear on those seed lines)."
If Texas Tech remains at least a #4, then this would be possible since there'd be us, Houston, Arizona, Kansas, and Tech.
