Can the Medieval executable be altered for a mod?

[Stazi]

Ok, checked the EULA off the VI disk. The paragraph on mods:
...
So I'm guessing no on changing the .exe.

Sad news but I'd like to thank you for your time and efforts. I really appreciate it.

• New Game Materials shall not contain modifications to any COM, EXE or DLL files or to any other executable Product files.

So..I'm not allowed to include in my mod anything that modifies com, exe or dll but may I add external link to a file or program which will do it? Eventually, may I add a detailed guide "how to do it" saying something like "you do it at your own risk"? It's not a rocket science, just hex editing.
