What dimensions do you need for the outside pocket? I suppose you want that gusseted so it's deep enough to fit a laptop with sleeve.
The cases I know have such a feature but the laptop pocket is the lower one. Not a detriment in my eyes. Keeps the center of gravity low. The upper pocket is a for the 311 bag.
here are a few examples:
