Think you might be over estimating how low those percentages are. Myself personally, and others, have played NPCs like King Elmer 50+ times and gotten zero drops from him. As a reference I've seen 15% materia melds fail about as much before I get a success.

I don't think it's lower percentages, I think it's just really skewed RNG that needs to be fine tuned to the sample sizes that an individual would realistically play. Either that ore make it like an achievement where beating an NPC X times will net you Card A and so forth. They could do this with materia melding where instead of a percentage you just need to use increased numbers of a given materia to overmeld higher slots.
