I have. It works if you remove the spacers and run one sprocket offset to the inside and one offset to the outside. Bigger sprocket on the inside. Roger

But the newer hbs have only about 0.150" between the dust cover and the snap ring. Brompton must use special, thinner cogs to make it work.

I used to use a modified Shimano freehub cog on the inside and the dished SA sprocket on the outside.
You could theoretically fit three if the inside and outside were dished and the middle one flat. Frank Berto once wrote an article describing how he did that. As I recall he somehow dished the inner (largest) sprocket himself.
