Use Mobile Responsive Menu Styles For Desktop Menu - Help

I would like the Desktop Responsive Menu to be the same as the Mobile Responsive Menu. Is there an easy way to make this happen or do I have to sort through all the code and make the changes in mychanges/styles.less?



Specifically I like the way the vertical menu works in mobile mode but not in desktop mode. Mobile mode looks much nicer and I would like to use that as my base and add some tweaks.



Thanks for any pointers.
