No.  You probably have to save the old position of the deleted window's
point in frame coordinates and have the function that selects the new
window use the window that is now at that frame position.  The function
would be called instead of the currently hard-coded

          mru_window = call1 (Qget_mru_window, frame);

and the call is fairly safe because the frame's first window has been
already selected at that time.
