That's not a thing xserver is set up to do, because that's not a thing X
lets you do. The list of depths is constructed statically at server
startup, and the only way to get the list of depths and visuals is in
the initial connection handshake; which means it doesn't happen, because
clients are not written to disconnect and reconnect. You could probably
hack something into working, but.
A much easier thing to do would be to simply export multiple _screens_
from the same display, each with a different depth, and then run your
rendering against the screen with the depth you want instead of trying
to switch the depth of a single screen.
