I've never used cursors in this way so my help is more theory but:
The called-function already created the cursors. In the parent function you
should simply be able to pass them through unaltered:
SELECT * INTO v_outvar1, ...;
swv_refcur := v_outvar1;
...
...
RETURN;
You can possible simply the above and toss the temporary variables but that
should not impact the semantics.
