Is there a way to use DMT to delete a group of items' Bill of Materials and the Bill of Operations, basically the entire engineered assembly for a group of items?

Should be very easy. Dump them out via baq and then check the delete checkbox and process.
Keep in mind that the DMT process for boos and boms does each row as a checkout, modify, checkin so you will need the ECOGroup ID to exist that you are going to process all of this on.

Optionally, you could delete the PartRev if you didn't want the revision.  It is much easier to delete the PartRev and add it later, than to delete the PartMtl and then PartOpr.
