bq: My question is if I can delete the field definition from the schema.xml and do an optimize and the fields “magically” disappears
no. schema.xml is really just about regularizing how Lucene indexes things. Lucene (where this would have to take place) doesn't have any understanding of schema.xml, so changing it then optimizing (and optimizing is also a Lucene function) won't have any effect. If you 1> change the schema and 2> update documents the data will be purged as background merges happen. But really, I'd recommend re-indexing into a new collection if at all possible.
