I'd appreciate help with the build scripts as I have work and little time to work on the module at the moment.
The main focus when I was creating this module was to replicate the Pixel's features onto my Xiaomi Mi A1 since we only have pure stock features with the stock ROM. With this module, it adds more customization elements which makes the phone even better.
I'd also look into how to backup the icons and layouts of the homescreens in order to keep the settings intact. For now, I do that manually by replacing the Launcher through Root Explorer.
I can help you. I can write these changes for you (what I suggested if you have less time for this) and also make the build script. I'll get back to this this evening when I leave the office.
