@Ronin:
The way I see it, there are many kinds of DF:
- Basic element DF: extremely and most powerful DF, including fire (ACE), ice (Aokiji), thunder (God Eneru)…
- Secondary element DF: not as powerful as Basic Element, including: sand (crocodile), buble (kalifa), candle (is it? - Mr.3), rubber (Luffy)…
- Animal Transform DF: bird, animal, human, fish, you name it. I.E: human (Chopper), horse (God's ride, the horse-bird), elephant (CP9 elephant sword - frunkfried), bull, giraff, hawk, wolf, dog, ...
- Transform DF: DF user who is able to manipulate the form of their body , including: copycat (Mr.2), flower (Robin), Seperate (Buggy), Jaw (Wapol in Rum Country)...
- Object Transformation DF: transform into object: steel, spike, spring ...
- Psychic DF: can manipulate other's thought/behavior, including: Painting (MissGoldenWeek), Mind Control(Donflamengo), Spirit (Shanks - I'm just assuming)
The two bolded at the top aren't logia, they're paramecia, as Oda has said before. The bottom two aren't devil fruit powers (Oda said himself Miss Goldenweek was more of a "hypnotist" and Shanks couldn't have a power. If he did, he couldn't have saved Luffy).
As for the topic at hand, yes, I do think the Rumble Ball could work with other DF users, but only Zoan type ones. Due to the nature of it (giving forms) I doubt a rumble ball would do anything to a logia or paramecia type because their devil fruit power gives them only one form. However, even if they eat one, they might not know how to use it, similar to Kaku fighting Zoro (Him accidentally going into his Giraffe/Human form) and Chopper using two rumble balls (the random thing).
