I've seen a lot of theorizing for their voice actors, one popular one being Danny DeVito & Willem Defoe, but I personally think Jim Cummings and Tom Kenny/Carlos Alazraqui should voice them and do voices similar to Pete & Ice King/Denzel Crocker. Though no one could ever replace Charles Martinet as their voices.
