Could you substitute some of the whole wheat for some rye? Maybe. say, 1?4 cup of rye to take the place of 1/4 cup of the whole wheat?

OR: Here is a recipe from my breadmaker cookbood, it's for light rye, but you could always add a couple of tablespoons of sunflower seeds at the add beep I think.

Makes 1 lb. loaf

7-1/2 oz water
1-1/4 c. white flour
3/4 c. rye flour
1 tbsp. butter
1-1/2 tbsp. sugar
1 tsp. salt
1 tbsp. caraway seeds (could sub. sunflower probably)
2 tsp. yeast
Mix on whole wheat cycle

Maybe try those and see what happens. Let me know, I usually make pumpernickel but would like to try this sunflower type.
