Epson has a little known program called "Epson Print Layout" that enables you to soft-proof ABW, including print toning. As I haven't used it much, I can't tell you how well it soft-proofs, but it does. It's still not going to give you standard presets, but with a bit of perseverance you should be able to get close to the toning you want without wasting too much ink or paper.
RMW's suggestion to use a custom profile means printing B&W using the color driver. In theory this uses more color ink in the mix than ABW, but how much more is not clear.
