I also have been using aosp apps that I've build from source using my ongoing aosp port(source can be found here and here.). The aosp ROM itself is not booting, but some of the apps built for the zaracl are working fine on the stock ROM(Launcher, keyboard, gallery and camera, etc). Give me a few minutes and I'll upload some of the apps to my google drive for download.

EDIT: Alright, here is the link. For the Keyboard, put the LatinIME in /system/app, and the libjni_latinime.so in /system/lib. I will be adding apps to the folder as I test them for functionality and make sure they are working okay. No guarantees, though.
