I've been thinking along the same lines as Bjornall. Lateral stability is not a function of the distribution of lift left/right/inboard/outboard, but rather a function of how the aircraft reacts to upsets of that distribution, and how easy it is to correct for this.
Along those lines, I would rather have the inboard portion of the wing generate most of the lift. If there is a gust then the resulting moment of roll will be less (moment = arm x force), compared to the situation where the outboard portion would do most of the work. And this means that less opposite moment (aileron input) would be required to keep the aircraft level.
I've experienced that long/slender wing aircraft such as gliders and a DA-40 are harder to fly in gusty conditions compared to short wing aircraft such as an R2160. Then again, there's also a difference in wing loading between these aircraft so their lower stability may not be entirely due to the larger moment generated by the larger wing.
