Beersmith 2 gives this:
6.7 lbs of Briess Light Pilsen LME
(use 5.75 lbs Extra Light DME if you'd rather)
Hop and yeast are all the same.
I would suspect you'd have the best results with the LME as the flavor profile of DME is pretty plain. In both cases, it'll still probably be lacking something as compared to AG.
If you're comfortable doing a mini-mash, change the LME to 5 lbs, and use 1.1 lbs each of the two grains per the normal mini-mash schedule.
