If you're prepared to make the class that originates SAX events implement XMLReader, then it's easily done using a JAXP identity transformation from a SAXSource to a StreamResult.

If you don't want to do that, and just want to feed events into a ContentHandler, then you can set up a pipeline in Saxon without too much difficulty: 

Processor proc = new Processor();
Serializer ser = proc.newSerializer(writer);
ser.setOutputProperty(....);
ContentHandler ch = ser.getContentHandler();

and then write to the ContentHandler ch.

Personally though if I'm writing XML from Java I much prefer the Stax XMLStreamWriter interface to the SAX ContentHandler. (People often forget that StAX has push APIs as well as pull). Getting an XMLStreamWriter from Saxon is just as easy:

Processor proc = new Processor();
Serializer ser = proc.newSerializer(writer);
ser.setOutputProperty(....);
XMLStreamWriter xsw = ser.getXMLStreamWriter();

I usually then front-end this with a custom class that knows about namespaces and possibly uses a chaining pattern, so the application reduces to something like

out.startElement("e").att("id", "23").att("name", "fred").text("content").endElement();
out.startElement("f").att("id", "29").att("name", "bill").text("content").endElement();

etc.
