You could break a chunk of flange off along the spoke holes, like separating stamps. The consequences could be ugly.

That said, modern hubs are not as low-flange and have fewer spoke holes. Both trends result in more metal between the holes. It also helps immensely that it is the NDS, with much lower tension anyway. So unless it is a low flange 36-hole hub, make sure it is solidly and uniformly tensioned and just ride it. Your wheel is in some pretty well-respected company as far as that configuration goes. Unless you find it ugly or otherwise irksome, in which case go ahead and rebuild it. You will only need half a wheel worth of spokes.
