If you know what you're doing, you might bend your bars OK. If I were doing it, I'm sure I'd kink the tubing and ruin the bars completely.
I think MichaelW has it right. There's actually a pretty fair number of North-Road-type bars available, ranging from inexpensive chromed steel to chromoly to heat-treated aluminum. Not sure what you might have ready access to, but in addition to the On-One Mary (which I've never used, but a lot of people like), you might consider the Nitto Albatross, the Soma Sparrow, and the Wald North Road.
