Nightly Cores For RetroPie (Raspian/Debian)?

Is there any chance to have the buildbot making a nightly (heck even weekly) build of cores for the Raspian/Debian OS that RetroPie uses?. So these could just be dragged and dropped into the RetroPie emulation folder, i know these cores are .so file type and thought that there were compatible with the Android cores but apparently they are not.
