Basically yes, but I suggest not to do it.  Reason is that not all
combinations actually do exist.  For example, it is possible in Pīnyīn
to have `xū' and `shū', but you can't have `shīn' while `xīn' is
valid.  Providing complete syllables is an aid to beginners to avoid
incorrect spellings, especially for people who are used to the
Wade-Giles transcription (which does have `shin' but no `xin').
