But round trunking required the wires to be disconnected and fished

No need to disconnect the Ethernet cable. A shrouded RJ45 plug will easily pass through 20mm trunking with room to spare. As the OP needs to pass 4 cables all he needs to do is tape the cables so that the plugs are one behind the other and they should pull through easily.
