This is not currently possible. The XIM fonts used are settable by
XEmacs, and therefore there should be a xim-face, which inherits from
'default. Implementing this properly will likely take some work.
In the meantime, of course, as a workaround you can change your X
resources and your default face, and start a new XEmacs.
