That would make them perfect candidates for body-mounted Kadee couplers. They should still be able to take tight curves due to the short wheelbase.
If you wanted to keep the standard 3 rail couplers, you could body mount couplers with a shorter shank to keep the cars close coupled. A little experimenting would show just how short the shank could be to allow operation on your curves.
Lots of different plastic non-operating couplers have been produced by Lionel over the years. Just snip them to length, drill the shank, drill the car body, and install with a screw. No need for a centering spring since they would be non-operating anyway.
Close-coupled cars with flanges on adjacent cars almost touching each other are what a string of ore cars is all about.
