TouchWiz Lollipop Kernels? topic

This is also about kernels in general. So, previously, I tried a "Note 4 Apps mod" meant for the International Galaxy S5 and my System UI crashed. I was wondering if my phone will mess up if I flash a TouchWiz Lollipop kernel from any Galaxy S5 variant – like AT&T's or Sprint's.
Also, getting back to the title of this thread, are there any S5 TouchWiz Lollipop kernels out there? I've been searching for a while but I can't find any other than ktoonsez.
