If you cut the Light DME down to 2.5lb, and lose the munich, you have what is almost a Witbier. I think that the high gravity you've got there wouldn't be balanced with the low hopping.
Even better, if you can rustle up a couple pounds of raw soft white winter wheat for the mash, you'll be golden. You can cut the extract down further in that case. My local hippie store carries it, as do places like Bulk Barn and even some grocers.
