Home Menu Nav. Button v.s. Custom Home Page

I have a custom home page that is my “splash page” with a 3-photo slide show on the “Origami Premium” theme. A “Home” navigation menu button is unnecessary as you can click on the header to get back to the custom page. When I delete the “Home” menu button, the custom home page also goes away. I need the “home” menu button space for another page as the home button takes up space and has pushed my new page to a second row, which I do not want.

Any solutions? Thanks.
(I did a search but didn’t find a solution to my particular problem).
