Understood..

However, even with say a disc brake upgrade there IS a "point of no returns" on how much extra braking can be provided before tire lock up on the trailer becomes a greater problem..

That is true, but he's having overheating problems, and disc brakes are simply superior for heat rejection. I know the feeling well too because it only takes 1 hard stop from 70 MPH on a downhill (6-8%) to cause brake fade in my tailer.

My concern is his car HAS disc brakes AND he is overheating them PLUS the trailer brakes..

EXCESSIVE SPEED combined with heavy braking will easily defeat even disc brakes.

Heck even big motorhomes can easily smoke brakes if they fail to use engine braking on long steep grades.

OP needs to do a few practice runs downshifting to see how more effective it can be to allow the engine to hold back..

Granted with a car you have gear ratios which will not be as helpful but it is well worth the try before sinking bunches of money into a bigger axle with heavier brakes...

OP also needs to put their "trucker hat" on for driving a towing combo.. You simply cannot drive as if you have no load behind you (AKA "sports car mode"). Use the posted trucker speeds when descending long steep grades basically anticipating and taking action BEFORE you start down a grade (IE NOT DOING 70 MPH downhill)..
