Well, anything is possible. Run-time files are :
jquery.hjt.megamenu.js
jquery.hjt.megamenu.css
you can get some template having it and copy parts from it to your site.
Tricky part can be module in menu option if you want to use it. You need to put extra module positions in template's index.php in hidden div block like:
<div class="megamenu_separator1"><jdoc:include type="modules" name="megamenu1" style="none" /></div>
<div class="megamenu_separator2"><jdoc:include type="modules" name="megamenu2" style="none" /></div>
...
