There is a problem with "this is equivalent to adding model references
to the relevant schema element". In particular, consider this scenario:

    <element name="ack"/>
  <operation name="a">
    <output element="ack" modelReference="a_ack" />
  <operation name="b">
    <output element="ack" modelReference="b_ack" />

This would be equivalent to 
  <element name="ack" modelReference="a_ack b_ack"/>
which is not what you want, if I understand it correctly.

Apart from this, your proposal sounds reasonable, yet I would like to
see more details - in particular, how exactly would your modelReferences
on the two ack outputs differ? Can you please give us the WSDL annotated
with any SAWSDL annotations that you would use there, so it's clearer
what exactly you want to do with them?
