You can only add a box like this to the right column on your main page, I believe. I think Wikia doesn't allow this globally. Also, I don't think there is an easy way to add a new pages list in the same format as Special:WikiActivity that just shows the new pages.

You could asks these questions at Special:Contact/general and maybe Wikia will give you some useful answers.
