Scratch this request. I achieved the desired results by modifying login.php - specifically the #login-modal (changed to the desire url for a full page login display
www.xxyy.com) and the DisplayType @line 65 (if ($params->get('displayType') == '
www.xxyy.com'). This did require creating two modules in Joomla, one for the 'login / register' links on the front-end, adding a specific module class suffix, then modifying those settings to only display the links, along with some css adjustments. Then creating a second sclogin module, applying any desired configuration settings and applying it to a custom position and loading that position in the desired article. Of course, to achieve the full page effect, that page has a custom template in Gantry template settings.
