Can you rename the files, instead, by adding _removed_by_rc.local.

     With this, Udev starts from scratch at every boot :-)

     Looks like a very nice approach, but it's too hidden: if you
inherit a machine which is doing that, it can take you pretty long
before you find out who the hell is deleting the udev rules. Maybe
rewrite the files with only a comment like

# This file has been wiped out by /etc/rc.local because I don't want
udev to rename my devices.
