Service [Q] Moto G Assist, Camera & Gallery for AOSP/CM

Hey guys,

I searched the web and haven't found much. What's really keeping me from going to a custom rom - be it GPE/AOSP (like Paranoid Android) or CM-Based - are those 3 features (Moto Assist, Camera, Gallery - even Radio FM). Sadly I only found negative evidence.

Are there any apks of those apps out there that work 100% on AOSP/CM-based roms? Or alternatives that have the same simplicity of design and functions?

Thanks in advance.
Cheers
