If this is possible, one might can do this, of course. Though, this procedure has to be repeated if the WRS-format changes.
Why don't you post your findings here? The first rule in cryptography is to publish protocols and how cryptosystems work so that possible attacks become visible and new procedures and algorithms can be used instead or old ones are being optimized to prevent future attacks.
Note: I do not provoke anyone to steal assets from foreign WRS-files or gamestudio games - I just think out loud that if it is in fact easy to break the WRS protection scheme why it should'nt be more secure..

I do not know if it's right to share my findings here, but if there is no objection from community and JCL i can share them.

yes for lite-c, no for wdl.
all code gets compiled in lite-c, but in c-script it's in the wrs file.

some shifting/shuffling based on the username/license password before or after compressing the data may be sufficent and fast enough if the key is saved in the exe/dll and not in the wrs.
