I put Nitto albatross swept bars on my Univega (wider flare than North Road bars) along with and Shimano 8-speed bar-end shifters. Works great. Going on two years with that setup. Only change I might make is to switch from the original 7-speed rear derailleur to 8-speed. The 8-speed shifters can cover the full cassette in friction mode but won't hold the largest 32T cog reliably in index mode.

I have most of a 10-speed Dura Ace setup, including bar-end shifters, if I felt a peculiar urge to convert a carbon fiber road frame to a plastic fantastic path racer with flipped North Road bars. Although I'm leaning more toward bullhorns for the bar end shifters. Dunno, depends on how weird I feel when I finally assemble those pieces.
