You might try Ilford Multigrade IV developed 1/3 the time in Photographer's Formulary TD-32 and 2/3 in Dektol. It should add just a little warmth to the otherwise neutral tonality. I used to do that with Selectol but haven't since it was discontinued. This thread was a good reminder --- I'm going to order some now.
