I imagine this works the way it does because pertex is just so breathable, your probably getting enough breathability just out of the 4" sides of the bag to not have an issue with condensation. Will this configuration also allow you to insert variable widths, in order to have 2 or 3 different selections for your trip?
Making a cuben bag would still give you the same issues as it is a WPB, but since you're having success with it, go for it.
