It is possible with CSS with something like:

.module-navlinks {
position: absolute;
top: 8em;
right: 0;
}

.module-navlinks * {
display: inline !important;
}

#header {
padding-bottom: 3em;
}

You may need to adjust some values depending on your font size. Also, with this method it doesn't always display fine in all sorts of resolutions and font sizes. The other method is via advanced customizations and a layer. If that's what you'd rather do I can try and see what I can come up with.
