Tim Rudman, who's book is often quoted, uses a Sepia + bleach/redevelopment in Thiourea process for his Iceland photos. He also likes Lith printing which is a far more complicated process.

Seeing this theme for warm tone, You could look to certian developers form the agfa bovira papers.The developers had a modified chemical profile to make the them papers warmer in tone.
I think the tones where due to -sulfite to -carbonate ratio just an idea ???
I have some notes on this BUT !!! I do not know for bw film neg to pos. ???
