Arch linux greeter without DM

I'm using Arch Linux with i3wm with xinit which results in having tty1 as my "greeter". I wanna know if there is any possibility to have a greeter, for instance, Deepin greeter at login prompt **without** having any display manager running. I am not sure if there is a way to call xinit before login and if that would solve the problem, but is there a way to achieve this?
