Yeah Jozus -could- be a match, but all we can do is speculate. Oda does whatever he wants and even if he explains SOME of his work with real life logic, other aspects are completely made up. But since speculations are fun, i could imagine Kizaru is Blackbeards natural enemy - after all the color black absorbs lightning fully. Aokiji is really a wildcard, like crocodile he has the ability to disable someone fully with just one touch...he just needs to get close. Remember, he only used a ranged ice attack on whitebeard, it wasn't his signature move "ice time", where he touches people and freezes them from inside as well (robin, jozu).

And as a third option you can forcefeed them another devilfruit, victory is guaranteed (2 devil fruits and your body explodes)
