What changes do you have in mind? Maybe someone else has ideas, or can do whatever things are best done as administrator.
I mainly mean cleaning up the front page, which has a lot of WikiWords (I can move pages to Non Wiki Words names even as a normal user, but I don't have the rights to update the links on the main page). Another thing is removing extremely outdated developer information, e.g. there was a page about "reprs", e.g. the version of our XML subsystem from before the conversion to C++. I don't think this page has any reason to stay in the wiki, because its content can be confusing at best. I would also move most links from the main page into subpages so that people can make their documentation visible more easily.
If regular users can be given only the rights to edit the main page and delete pages, then of course I would settle for that.
