i think what @migumbo is more concerned about is the DOM ang page html/php level with a flat html site and the responsive-plus-wordpress site. for me if the navigation links, sidebars, footers will be all the same with the new responsive-and-wordpress site with the old one google wont notice, as for my experience with moving flat html sites(with over 15k pages) to mambo(it was mambo by then 2004 before we move it to joomla! in 2007) it traffic was the same. having the exact same method of keeping the exact url and metas from the html site to the mambo site. no traffic difference based on the cPanel stats(we dont have google tools by then). so on my experience in addition to as what @louieramos mentioned about js; the li's and ul's in the navigation wont matter to google even completely and differently implemented in a new site. IMO, what google will give weight is the links/url's contained in the navigation and NOT how the navigation was implemented(pure css, suckerfish, etc)
