More/ more of

The X-Files was converted into a comic book series written during the show's third and fourth seasons. The initial comic books were written solely by Stefan Petrucha. According to Petrucha, there were three types of stories: "those that dealt with the characters, those that dealt with the conspiracy, and the monster-of-the-week sort of stuff".^{http://en.wikipedia.org/wiki/The_X-Files#cite_note-comix-164} Petrucha cited that latter as the easiest to write. Petrucha saw Scully as a "scientist […] with real world faith", and that the difference between [Mulder and Scully] is not that Mulder believes and Scully doesn't; it's more a difference in procedure."^{http://en.wikipedia.org/wiki/The_X-Files#cite_note-comix-164} In this manner, Mulder's viewpoint was often written to be just as valid as Scully's, and Scully's science was often portrayed to be just as convincing as Mulder's more outlandish ideas.^{http://en.wikipedia.org/wiki/The_X-Files#cite_note-comix-164}

I'd like to know whether "more" modify the clause incorporating it, not "is" and whether I can displace "more" with "more of" without meaning change, in my example.

Thank you in advance for your help.
