Crawley's FX6a works well with paper but you'd need to play around with the Thiosulphate level (70-125g)and perhaps add bromide or benzotriazole, additional Hydroquinone increases the bcontrast as does lowering the Thiosulphate

Monobath FX6a
normal speed

Hydroquinone 12 gm
Phenidone 1 gm
Sodium sulphite (anhyd) 60 gm
Sodium hydroxide 10 gm
Sodium thiosulphate 90 gm
Water to 1000 cc

I did a lot of work on Monobaths commercially in the late 1970's and we had planned to market one specifically for papers, I've got my notes somewhere in storage
