Mega Menus - Site Links - Bottom of the Page

[Runner2009]

Here are the questions:

If you replace your top menu with a mega menu - like rei.com, target.com etc - that has dramatically more links and lots of non-optimized testimonials and calls for action, and locate the actual code of the mega menu at the bottom of the HTML , How will this affect your sitelinks?

Will this now, make your on-page content more visible and indexable? Or does the Google bott dismiss this as just navigation content?

In the past, I've have seen this technique work well, but that was before site links were easier to obtain.  Looking at sites with virtually no navigation on their home pages and good authority, I've seen site links seemingly gleamed from alt attributes.
