themability

what is the best way to approach themes of the wm, for those who are interested in this (I believe all people have a minimum aesthetic demand)
the way leftwm approaches this is to have two config files,, one for functionality (keybindings etc) and other for themes, would this be sensible
themes would include colours, background, font, opacity, borders, gaps etc
would switching in and out bars (polybar etc), docks (eg latte-dock) and panels (mate-panel) be able to be supported? [I'm not sure how they would fit into the above config scheme, presumably their config files would be separate]
