I would reset RPROMPT periodically instead.
Maybe something similar to :

  % my_jobs() { RPROMPT=$jobstates }
  % precmd_functions=(my_jobs)

But this is just for testing because you will certainly clutter your
rprompt this way.
Don't forget that if the line is too long, the content will not be displayed.
