To implement a new layer 1/2, you need to subclass the NetDevice and
Channel base classes. For layer 3, you would need to use the
Node::RegisterProtocolHandler/UnregisterProtocolHandler methods to get
packets and you would need to send packets using NetDevice::Send. (The
src/internet-stack/arp-l3-protocol.cc class does this)

PS: although it's not a big deal, I think that this is probably  a
question better suited for ns-3-users:
