  You could do that if you wanted to, but it's a lot of trouble for nothing.
The reserved blocks are not used by NetBSD, so changing them will have
no effect.

  The NetBSD FFS filesystem already has 8K reserved for the bootloader.

  That's correct.  I suppose you could create a customized bootblock by
modifying the memory configuration code to specifically set your memory.
I'm not certain that there would be enough room in the bootblock to add
very much, but then since it's a custom bootblock, you could remove any
extraneous code not required by your system.
