Actually this should be possible. Use SiteMenu as configured in mitchinson-earthy and use PageMenu as configured in styelshout-refresh. you will need to also harvest the stylemenu.css from styleshout-refresh (or it might be styletreevew.css)
The result will be a horizontal menu with flyout sub menus and a vertical menu showing child pages of the current page and duplicating some of the menu items in the main superfish menu.
Best,
