Preheat oven to 400°. Cut pumpkin and squash in half lengthwise, cutting through stem and bottom ends. Reserve seeds for another use. Place pumpkin and squash halves, cut sides up, in an aluminum foil-lined shallow pan.
Microwave 2 Tbsp. butter in a microwave-safe bowl at HIGH 25 seconds or until melted; stir in 1 Tbsp. honey and 1/4 tsp. salt. Brush cut sides of pumpkin and squash with butter mixture.
Bake pumpkin and squash at 400° for 45 minutes or until tender. Let cool completely (about 15 minutes). Scoop out pulp, discarding shells.
Melt remaining 2 Tbsp. butter in a Dutch oven over medium heat. Add onion, and sauté 5 minutes or until tender. Add thyme; sauté 1 minute or until fragrant.
Stir in broth and pumpkin and squash pulp. Increase heat to medium-high; bring to a boil. Reduce heat to low, and simmer 10 minutes. Remove from heat, and let cool 10 minutes.
Process soup, in batches, in a food processor or blender until smooth. Return soup to Dutch oven. Stir in half-and-half, next 4 ingredients, and remaining 1 Tbsp. honey and 1/4 tsp. salt. Cook, over low heat, stirring often, 3 minutes or until thoroughly heated. Serve immediately.
