Alternatively, one of the recipes for making negatives might give you a better tonal scale. I have used John Coffer's "#7 for Negatives" for making ambrotypes and found it quite good (it has two iodides and two bromides. Email me for a recipe: castlebravo "at" icloud "dot" com) But the Coffer #7 still calls for Ethanol and Ether, so I'm not sure that helps you.
Have you experimented with making a negative developer and leaving it on the plate for a minute? That might be worth exploring.
