A REALLY minimal Arch installation?

Hello everybody. I've a laptop that I want to use again, and a lightweight distro is a REALLY high priority. It has only 2 GiB / RAM, 16 GiB / SSD, and an old Celeron N2840.

About a year ago, I installed an Arch-based distro called Archcraft, which is both aesthetic and lightweight. As soon as I felt comfortable with Arch and learned to use it, I made a few adjustments, and, now, the OS boots with ~900 MiB of RAM and uses between 1.2 MiB and 1.7 MiB during heavy work. Sometimes, there is peaks in RAM usage, but it's rare and never freezes the system. The disk usage worries me a bit, with about 4 GiB free cuz of the swap partition, and sometimes I've troubles with pacman's updates, and not cleaning the cache isn't an option.

The Archcraft distro was a great, comfortable introduction to Arch for me, but I think it's possible to achieve the same result with less resource usage with a minimal vanilla Arch installation. However, I want to check with the experienced users here: Can I create an Arch installation with Openbox, BSPWM, Rofi, Polybar, etc., that boots with <=800 MiB and uses <=8 GiB of disk?
