Membership site and wikipedia mixed in with detailed graphics

Hey :slight_smile:

Okay ... so my design concept is this; i'm building a multisite network within a particular visual theme.

I'd like to set up a membership site and a wikipedia with a fairly extensive graphical interface. More pictures, less text. Like a superhero or mythical database, visually rich.

Can the wiki and buddypress themes do that? Can I deeply change the top-level visual format and still work on top of the framework?
