P8Lite - Is it possible to install Contacts App from Stock Marshmallow into Nougat?

[derei]

I'm really having hard time accepting this Google Contacts app that comes into Nougat... but I really enjoy the Contacts app that is in B896 (Marshmallow - EMUI 4.1) for Huawei P8Lite. I tried to back-up the app and install it, but for some reason it didn't work (said the app seems corrupted, but I doubt - rather I did something wrong or not compatible).

So, if it is possible to use the same Contacts app, I would very much like to use it. Also, if anyone can provide the APK file, please do so for me.

Thanks.
