I could try some infill though I'm far from convinced it's the joints that do all the drooping. I think a lot of the droop is just pipes bending further forward in the frame as the load is applied at the rear. Your post has got me thinking about removing the suspension at the rear though. That would allow substantial reinforcement directly under the cargo area. That'd mean loosing the ally swing arm and replacing with steel and probably two steel poles directly up from the rear wheel to brace.
Using panniers would also mean loosing the ally swing arm and adding a little steel to form pannier mounts so probably about the same extra weight for both suggestions. Looking like a choice between keeping the cargo area and keeping the suspension. I'd originally put the suspension in for two reasons:-

- To take a little stress off what was a longer than usual T chassis.
- Because the suspension was probably lighter than not having it or at least no heavier.
