Gremlin return one out vertex of current traversal

If currently traversal includes [v1, v2, v3], v1, v2, v3 all have multiple out vertices,
is it possible to use gremlin to return one out vertex for v1, v2, v3?

E.g., 

v1 out: [v4, v5]  
v2 out: [v6, v7]  
v3 out: [v8, v9]

Hope result can be sth like: [v4, v6, v8]

If you want to choose one of them in an arbitrary way you can use local and limit:

g.V().hasLabel('v1', 'v2', 'v3').local(out().limit(1))

if you have some logic to the filter you can do something like this:

g.V().hasLabel('v1', 'v2', 'v3').local(out().order().by('value').limit(1))
