I haven't experienced a ceramic version, nor humbucker-sized, but the latter shouldn't make much noticeable difference.
The AV 'Pig was absolutely massive - "throaty" is the word that comes to mind. You do get a nice amount of low end detail with a single coil, but the ceramic magnet would definitely be a good call if you're playing at very fast tempos.
I do play DM from time to time, but I can't remember if I did so when we did the clips. The 'Pig 90 can certainly cover the same ground as the Warpig though, so if you want that level of saturation and aggression but with some P90 midrange character then it seems like it'd be perfect for you.
