Stephen suggests "why not reverse a black and white paper stock?".
Back in the early 70's, while at University, I went to a lecture about processing your own B&W slides and making B&W reversal prints. The lecture was given by someone from Birmingham School of Photography (UK), he showed some excellent images, with a very long tonal range. He claimed that this method gave far higher quality than the conventional negative/positive process.
I'd never heard that before and certainly haven't heard it since, but he did have superb prints, so it's worth trying. There are plenty of articles about reversal processing of B&W paper.
A reversal print will definitely give a higher quality than go through another film stage.
