They could always get new voice actors, like Alejandro did.

As for Cody, they already didn't include him in TDAS because they thought his plot was over. Ezekiel is rather obvious. We should be happy he still got somewhat "happy ending". Although he may still have cameo appearances if the season would take place on Boney Island (which I doubt).
