Since clone creates a separate tree, that won't happen.
Note that a viewport doesn't need a clone to work, you can add parts of
a tree to different viewports. (The SimpleSceneManager is a different
beast, though). I don't know if that will work in your case though, but
it's worth keeping in mind.

I have a function that looks like this, it replaces a core instance
everywhere. You could perhaps use the same thing to do subChild:
void MyNodeWrapper::replaceCoreEverywhere(osg::NodeCorePtr& core)
{
assert(core);
osg::NodeCorePtr oldCore = m_node->getCore();
const osg::MFNodePtr& parents = oldCore->getParents();
for (size_t i = 0; i < parents.size(); ++i) {
osg::NodePtr node = parents[i];
CPEdit(node, osg::Node::CoreFieldMask);
node->setCore(core);
}
}
