I think looking at what Western devs were making and saying "ok but what if you put Nintendo characters there" was kind of a Miyamoto thing back then, nothing to do with warring. Do y'all remember Star Fox Adventures?
And that's why it was a big character development moment when the Splatoon devs (a new team of rookies making their first game at Nintendo) asked him to let them use Mario characters, and he mentored them to create their own characters instead, to give Splatoon its own identity.
