Yes, I would volunteer to mentor this project.

That's a good summary from a high level.

If you're looking for pointers into the code for where 
StAXSource/StAXResult would apply, here are the main entry points:

[1] 
http://svn.apache.org/viewvc/xalan/java/trunk/src/org/apache/xalan/processor/TransformerFactoryImpl.java

[2] 
http://svn.apache.org/viewvc/xalan/java/trunk/src/org/apache/xalan/transformer/TransformerImpl.java

[3] 
http://svn.apache.org/viewvc/xalan/java/trunk/src/org/apache/xalan/xsltc/trax/TransformerFactoryImpl.java

[4] 
http://svn.apache.org/viewvc/xalan/java/trunk/src/org/apache/xalan/xsltc/trax/TransformerImpl.java

specifically the newTransformer() and transform() methods.

Looking forward to seeing your project proposal.
