Could get away with a single shifter if it's only RD. TTF probably have people splitting sets.
If you only run one shifter and one derailler do you still need a Junction A and Junction B? Could you get away with a single 3-port junction A?

Junction A (3 port)
- Shifter
- Battery
- Derailler
Need longer cables but what have I missed?

As I understand it you need two junction boxes, even if you’re only running a rear derailleur.

I’m currently accruing the parts to do this on my cross bike, as I’m going to run Hylex with the climber button modification. TRP say you need two junction boxes.

I don’t think you do.
I remember testing this and being able to just use one. And it could be a b box also. But it was a while back, and my memory is poor.
