Managed to dirty flash it on lavender (doesn't work with a clean flash, provision error on Google config, right before jumping to the mi cloud settings) but some apps like Facebook, linkdin now exhibit erroneous behaviour, like they don't load at all. Maybe some error with the Android webview stuff that was described in this thread already?
Edit: managed to fix the app stuff, was a simple case of clearing cache on those apps. The only thing that is bothering me so far is the battery consumption. Also the quick charge animation is fixed now from 9.3.28
