Might be a bit of a stretch, but what you are referring to could be considered a form of parody. In copyright squabbles, parody is often considered to fall under the fair use clause of copyright law. Judgement of whether a fair use is indeed a fair use or an infringement considers the following factors:
1) the purpose and character of the use, including whether such use is of a commercial nature or is for nonprofit educational purposes;
(2) the nature of the copyrighted work;
(3) the amount and substantiality of the portion used in relation to the copyrighted work as a whole; and
(4) the effect of the use upon the potential market for or value of the copyrighted work. The fact that a work is unpublished shall not itself bar a finding of fair use if such finding is made upon consideration of all the above factors.
This is probably redundant info to you, but there it be anyway.
