I have had good results from developing normally, and then if I really really want a long-scale negative to bleach it and redevelop in a staining developer. One rather anaemic negative ended up printing well on POP, with a longer range than the 21-step Stouffer wedge I put beside the negative...
Incidentally no process needs high density. The critical thing is the contrast, also called "scale".
