Josh,

totally untested and from a dark corner of my brain, but this would be my method (as a baseline):

STARTUP MOUNT; ALTER DATABASE DATAFILE Ď<datafile name with complete path>í OFFLINE DROP;
          for all datafiles which does not belong to system, undo, (sysaux?), (temp?), <yourTS>

ALTER DATABASE OPEN; DROP TABLESPACE <tablespace name> INCLUDING CONTENTS;

          for all the not-wanted TS.

this is just a graph of an idea, not a walkthrough.
