With enrolments in STEM degrees going down, I think that another dedicated Sci School is definitely needed over a humanities one. Of course, humanities are important, but with the enrolments in Law, Arts and Comm (to a degree) degrees in universities being generally quite strong, I think that this is a good move. I can say, without bias, that UoM has been using it's prestige and recognition to ride through the uncertain waters of the Melbourne Model implementation. It's dying down a little, with enrolments going back up (citation needed here, but 5 of UoM's degrees were the most popular preferences or something last year) but I think that the collaboration with extra-university agenda's is ultimately a good move to show a more holistic university.
