Pick through the crabmeat and remove and discard any shells; set aside. Grease the insides of the ramekins with butter. Lightly sprinkle the bottom of each ramekin with salt.
Whisk together the mayonnaise, 2 teaspoons of the Dijon, 2 teaspoons of the lemon juice, the Worcestershire and hot sauce and 1/4 cup of the panko in a medium bowl. Gently fold in the crabmeat and 2 tablespoon of the herbs. Season to taste with salt and pepper. Add up to 1 more teaspoon of the remaining lemon juice, if desired.
Divide the crab mixture evenly among the ramekins. Using the back of a spoon, create a small well in the center of the mixture.
Gently crack or slide 1 egg into each well and season with salt and pepper. Spoon the creme fraiche or drizzle the heavy cream around the eggs, evenly dividing it among the ramekins.
Place the ramekins inside a baking dish and transfer to the oven. (You may also want to place the baking dish on a baking sheet to catch any spills.) Carefully pour enough boiling water into the baking dish to come 3/4 of the way up the sides of the ramekins.
Bake until the egg whites are just set, but the yolks still jiggle when you move the baking dish, 15 minutes to 30 minutes, depending on the size of the ramekins.
Meanwhile, heat the oil over medium heat in a small nonstick skillet, and stir in the remaining 1/4 cup panko. Cook, stirring, until toasted, 2 to 3 minutes. Stir in the remaining 1 teaspoon Dijon. Remove from the heat and season with salt and pepper.
When the eggs are done baking, carefully remove the baking dish from the oven. Using a thin spatula and oven mitts and/or tongs, carefully remove the ramekins from the water and set on a kitchen towel to dry the bottoms. Transfer each ramekin to a plate, top with the toasted panko, and sprinkle with herbs. Serve with toasted bread and salad.
