Fusing fixed-nav with Bootstrap

I think the fixed-nav is one of the best no nonsense top bar navigation
systems out there. Bootstrap has hundreds of lines of code just for top
bar nav and most of it one would not use. So why have excess css in
your project?
So I am attempting to hybridize some of the core components of
bootstrap, just those I need and fuse it with this fixed-nav. This is
just the beginning, I plan on fusing some of the other great HTML5/CSS3
projects that have been posted here. Ultimately my target is to build
this into a SharePoint 2010 site. SP is heavy enough with all the CSS
it generates on the fly and I feel dumping a full blown bootstrap on it
just adds fuel to the fire of responsiveness as in how long it takes
the page to load.
