I don't think so, it would make an even sharper bend routing the cable through the bar. And I don't have a drill!
this would depend on where you drilled the hole. Could go through twice and run the cable on the outside rather than the inside of the bars. This would make for better routing, but as 6pt has pointed out a little less curves in your cables may make for some extra curves in your nose/collar bone further down the line....
