Yeah, I've built some of these left-side radial wheels without any problems. The only issues I've seen with hub-flanges have been due to multiple wheel-builds with different lacing-patterns. This ends up cutting up the hub-flanges in multiple angles. The final build using radial just happens to be the last straw for the flanges. If you use a new hub, and build it first with the radial left side, I doubt you'd have any problems.
