Can I replace Android Userspace with BusyBox?

‎Hello everyone, Im interested in an experiment and I'm looking for some technical guidance ‎Since Android uses a modified Linux Kernel, I want to see if it's possible to remove the Android Userspace compeletly and replace it with a Minimal BusyBox Userspace. ‎ ‎ ‎So my goals are: ‎1.Boot directly into BusyBox shell ‎2.Run standard linux programs compiled for my device's architecture ‎ ‎But my questions are: ‎Are there existing projects that have already made this other than PostmarketOS (PostmarketOS hangs on boot) ‎And is it even possible to make this? I'm not sure if its possible or not since I could not find any source that talk about this ‎ ‎My device is: SM-T280 or GTEXSWIFI and it uses a DHTB header

The reason I want to do this is for device efficiency and learning, It's a really old and extremly slow Tablet with android 5.1.1

‎And sorry if I had any grammar mistakes
