sprockets for Sturmey Archer 8 speed hub?

I have changed sprockets on SA 3-speed and know that SA and Shimano sprockets will fit the 3 speed (Shimano with a little grinding). What about diff. sized sprockets for the SA 8 speed hub? Are they available? the same as 3-speed? I'm asking here before going to the trouble of taking mine apart. (This is a Terratrike recumbent trike with the 8 speed hub.)

The driver/ sprocket interface on the 8 speed is larger than the 3 and 5 speed, so they are not interchangeable. I think 23 or 25 teeth are your options.

The 23T and 25T are offered in both 1/8 and 3/32. They are dished. There's also a 20T, 3/32, flat cog (HSL897).
