You can try.

Did it work?

I tried to use XFCE4 with Ubuntu on a chroot jail, but I wasn't able to get it working.
At the least I was able to find out what the problem is, which in my case was that the user id and group id for the Wayland socket wasn't accessible between Termux-x11 and XFCE4.

XFCE4 required the socket to be set as root , but then if you chmod it for that uid, the Termux-x11 app won't be able to read/write to the socket, thus failing to render the GUI.

I tried a bunch of ways to make the same socket accessible to both XFCE4 and Termux-x11, by trying bind-mount on chroot and via a rooted terminal on android, linking the file, changing the XDG runtime on Termux-x11 to another directory... But still wasn't able to get it working due to these permission issues.

Android uses a different user id and group id for each app (for security reasons), and this is what is causing the problem in this case.

Here's a visualization of the problem in question, u_729 will be the Termux-x11 UID and GID used in this example:

Socket	User	Group	Problem
wayland-0.lock	root	root	XFCE4 will be able to read/write to the socket, but Termux-x11 won't.
wayland-0.lock	u_729	u_729	Termux-x11 will be able to read/write to the socket, but XFCE4 requires the socket to be both user and group set to root
