Stock Kernel

Hi
I've modify my asus me176c kernel, rollingback to kitkat from lollipop like in this xda post: https://forum.xda-developers.com/memo-pad-7/general/how-to-rollback-lollipop-to-kitkat-t3422498
I want to install lolllipop again (for app's compability resasons) but i can't update the device..
It's possible to build a 4.4.2 rom that includes kernel "install" and then finally update to lollipop?
Thanks in advance!
