As a long-time higher education faculty member and developer of an early campus website (mid-1990s) who despises many of the built-for-higher-ed content management systems and who uses wordpress extensively... I'll just say that I think this sounds like a fine idea.

Right now it is difficult to get traction on behalf of wordpress with campus IT folks, who don't understand wordpress, much less how to use it in an academic context. They tend to write it off as some kind of funky blogging tool, and they believe that the expensive commercial products are the only viable tools.
