I took a look at the achievements customization page, but it looks like the only new badges which can be created by local administrators are for editing a particular category. Otherwise, that page just allows us to customize the names/images of existing achievements.

More in-depth customization is probably only available to Wikia Staff. (And I recall reading recently that Wikia's development team probably won't revisit the achievements system any time soon; they are apparently preoccupied with Project Darwin.)
