After buying some sheets of 1mm carbon fibre sheet/plate on eBay and marvelling at its stiffness, have been thinking...
Imagine if someone made an insert to fit inside the rear mudguard(fender) from carbon fibre that had steel inserts that picked up the top suspension mounts as well as low down - somewhere on the z-plates and also extended rearwards past the frame loop?
It would act as a structural item to support the back of the loop through the mudguard(fender).
In effect a bolt-on reinforcement.

Just crazy old meanderings or worth pursuing?
Be gentle!
 
I believe the police bikes used to have bits of angle iron welded to the seat loop to support the panniers etc
With the rack I made for my commando I made sure the side rails were strong and pick up o the pillion footrest mounts
I prefer it to bolt at this point rather than just rest there, because when you go over a bump whatever you have stowed on the back ie top box panniers wife/girlfriend or both!!
Want to go upwards with considerable force
Your idea sounds good if you could make it so it's not intrusive
If you do it I'd like to see photos, there's quite a lot of shaping and offsets to cope with there
But it'd be great if you got it to work

Either Craven or a UK police force made special brackets for a BMW boxer to carry a police radio and Craven panniers, Norton in the 1960s supplied a cut out fuel tank for the radio.
as for the rear mudguard, the deep valanced steel type were not reinforced as far as I know, but the lighter alloy type could do with a alloy channel bent to concurs underneath to reinforce the mudguard.
 
The Interpol pannier frames were bracketed to the seat loops and braced to the pillion footrest mounts. The two that I owned did not have any additional bracing of the rear frame loop. The top box, were fitted, was mounted were the passenger seat would have been. This would have been considerably less stressful to the rear loop than your 15 stone mate! It’s mainly the interstates that suffer loop droop due to the, longer tank and seat, the touring nature of the beast and therefore the increased weight on the back.
 
Interstae ; that'd be because the pilots furthest aft . Therefore a pillion is ON the rear loop .
Whereason the others he / she / it , is 1/2 on the shock mount area .
Particularly under breakng ! . er , Brakeing .
