If you are handy with ResEdit, nuking the icons shouldn't be too hard--
just make them the same pattern as the screen, or, better, use a
dissassembler, find the JSR to the showicon routine, and NOP it out.
Problem is, INIT-31 won't execute invisible files.  The best you could do
to hide the rest of your files would be to create a partition (with
SUM-II or SilverLining or something) that requires a password, and doesn't
show up on boot-- then they won't even KNOW you have those naughty files.

You could try naming all your INITS "Microsoft Word Bug Fix #n"
