No, you can't.

su root
cp -pR /boot/kernel /boot/good

Where does DEBUGDIR enter the picture?  The above will copy
both kernel and kernel.symbol to /boot/good.  With your scheme
one loses kernel.symbol (along with all other *.symbol files?).
If one escapes to the boot prompt, she can do 'boot /boot/good/kernel',
will the boot process automatically find a (nonexistant?)
/usr/lib/boot/good/kernel.symbol.
