Hi Jagger,
Thanks for your interest.
No, I did not find a way to make the JUGA menu work in this template instead of the default mod_mainmenu module.
I ended up creating a separate menu with the module mod_manimenu_juga (provided by the JUGA people) to publish the items that are restricted by the JUGA component. I also made it only viewable to JUGA members after logging in. I made a special post-login redirect landing page which contains instructions on how to access their restricted items in the JUGA menu
Not as slick as using the default mainmenu, but it works.
Best,
railer
