I would welcome a re-styling of Perlmonks. Most of what's needed can be achieved by "Just" applying a nice(r) CSS stylesheet, as most of the themes available are implemented through stylesheets anyway. If you find elements that cannot be (conveniently) styled, adding id tags it hasn't been a major obstacle in my experience. So if you have (access to a person with) graphical/design skills, it sould not be hard to restyle the site and make the theme the default for Anonymous Monk.

Making the website rely on Javascript (jQuery) by default would be undesireable for users on mobile connections, as I don't consider surfing Javascript-heavy sites with mobile phones desireable.
