I do not get how this would make anything easier or safer, but...

The boot loader won't find your /etc/boot.conf at wd0b (searches at
wd0a, if I read boot.c, ..., dev_i386.c correctly).

I guess you could patch it, but I'd say you are creating a monster.

I still do not get the point of this exercise, but could not wd0a be the
default boot device and wd0b the alternative?
