To do this you'd have to have a custom cull traversal and apply the state and then call the drawable. It's rather messy. Why not just use the OSG's inbuilt ability to use multiple render bins and place the bin number after everything else. To get SilverLinning to work with this you'd need to also create a custom Node and Drawable to wrap up the required calls but this isn't difficult, again you can use rendering bins to control the ordering.
