Question Adding Peak/Off-Peak Time Support to AOSP Email App

I am considering a project to add peak and off peak time configuration to the aosp email app. I have zero android or java coding experience and my general coding experience is limited to some pretty simple php. However, this is a feature I greatly desire, and my searching tells me others do as well.

I was wondering if anyone could tell me if it is feasible. Any advice on where to start?
