I would think that a rootless x-on-wayland would have to implement a 
fake X11 window manager that knew how to talk to Wayland. The window 
manager hints and messages is much to baroque for any simple 1:1 
translation. Also this window manager would have to draw the window borders.

The actual X11 calls to resize windows (ie on an override-redirect 
window) would translate directly to changing the size of the Wayland 
window, not to the wl_shell calls.

Rootless X on OS/X and Windows has been done and some of these questions 
must have already been addressed there.
