I do not know about you, but I prefer adhereing to the law than to
break it in a way you have the best chance of getting away.
As was stated before, proper clean room implementation makes it impossible
to have undeliverately copied something protected. With all the
specifications made you also get a good documentation of what actually
happened. Noone can force you to make it more 'different' to the orginal
(and even less to make less verbatim copies, because there are no
 verbatim copies, only things ended up to be verbatimly the same).

The only possibility to attack this scheme it to persuade to court
you did not do so and lied and produced specifications and
documentations and the like to disguise the facts. It is not even
your word against someone else's word, but your word against someone
else's wild guessings.
