I just did it in training mode so I know it works.
In fact it looks like you can start it off a 5C too and it works fine.
I didn't use the hop. I never use the hop, really. The hop just helps you get the delay right, but if you delay on your own then it's fine.
I didn't need to do anything special, so it's the same technique you would use to connect any other j.B > j.A > 2C link. You have to delay the j.B after the first 2C, and the j.2A after the j.B.
