Has anyone ever tried making a CR2 with two figures sharing one or more of the same actors and welded together to see what it does? For instance:

actor BODY:1 {
...
}
actor BODY:2 {
...
}
actor hip:1 {
...
}
actor neck:1 {
...
}
actor neck:2 {
...
}
actor head:1 {
...
}
actor head:2 {
...
}
actor abdomen:1 {
...
}
actor chest:1 {
...
}
actor lCollar:1 {
...
}
actor rCollar:2 {
...
}

figure lTwin
  {
  name leftTwin
  ...
  rootActor BODY:1
  addChild hip:1
         BODY:1
  addChild abdomen:1
         hip:1
  addChild chest:1
         abdomen:1
  addChild lCollar:1
         chest:1
  addChild neck:1
         chest:1
  addChild head:1
         neck:1
  ...
  weld abdomen:1
         hip:1
  weld chest:1
         abdomen:1
  weld lCollar:1
         chest:1
  weld neck:1
         chest:1
  weld neck:2
         chest:1
  weld head:1
         neck:1
  weld rCollar:2
         chest:1
  ...
}

figure rTwin
  {
  name rightTwin
  ...
  rootActor BODY:2
  addChild hip:1
         BODY:2
  addChild abdomen:1
         hip:1
  addChild chest:1
         abdomen:1
  addChild rCollar:2
         chest:1
  addChild neck:2
         chest:1
  addChild head:2
         neck:2
  ...
  weld head:2
         neck:2
}
