Why don't you try Pyrocat HD or adapt the Diafine type formula. Alternately look for some of Barry Thorntons published two bath formula.

The original Promicrol would probably be the closest to what your looking for, or Agfa Atomal. Calbe make a reformulated version of Atomal A-49 using CD-2 and Pyrocatechin, there is a formula posted on the internet. And then you could look at Crawleys FX10.
