This is a good idea, in my experience. YMMV, of course, but I have always found that having brooks saddles just fractionally nose-up works, because it prevents you sliding forward and placing your weight on the narrower part of the saddle - which, of course, means placing weight on the perineum. The other thing you could try is lowering your seatpost just a tiny bit - even a couple of millimeters might make a difference.
