Guys, I just had a thought that might help.
Rodinal has a VERY high level of Sulfite compared to color developers and the Sulfite is a powerful competing agent for oxidized developer and thus prevents dye formation. A special mix one-shot of pAP with low Sulfite might give you much more intense dyes. IDK, just a thought. I am not sure of the final level in the working solution but I would try to reduce it by 50% - 80% just as a test, if possible.
