This could possibly reduce your code size to below 64K - although it would be more difficult to debug (even with an ICE).

my experience:
"although it would be virtually impossible to debug (even with an ICE)"

Re code size reduction: I have learned that thai can be accomplished to a very large extent by "helping" the compiler.

an example, albeit small, that I see very often:

if (variable == TRUE)
{
  variable = FALSE;
}

why not just
variable = FALSE;

which is both more compact and faster.

Sometimes it really pays to check 2 versions of the same code e.g. "do while" and "for" can be used interchangeably in most cases, and have a look at the generated assembler. Then jot down in your DNA computer which to use.
