@LateNightLinux could try, but that would be hard. Although I am one of them that got converted, I already have been dual booting Linux and have an old laptop running Linux already at the time. Most people use WSL because there are things that only runs in Linux and it is hard for them to step out of the comfort zone.

But if trying to convert, I think just make sure they are not using way too niche software or playing games that cannot run on Linux; Running lightweight WM or DE on WSL could be a great introduction to WSL people, with xfce and KDE a good starting point (although not sure KDE is able to run on WSL right now, literally no longer use Windows except testing with WSL)
