I think Ferrari can wait, unless they have already decided that they don't want Vettel/Leclerc for 2020.
AFAIK Vettel still has a contract so unless they decide they no longer want him, they will assume he will be back.
I think Ferrari realize they will not be able to lure Hamilton or Verstappen for 2020 anyway.
Should Vettel decide at the last minute he's had enough, they can always offer a 1 year contract to the one that misses out on a Renault seat (Ricciardo/Hulkenberg/Ocon), or even Kvyat (was their test/reserve driver), Giovinazzi, Raikkonen. Or Perez. Or Bottas if he'd be out at Mercedes.
A 1 year contract, if he surpasses expectations you can keep him, otherwise go for a higher-profile driver or one of your juniors (Schumacher/Shwartzman/Armstrong/... who else) -- a lot can happen in a year (and a half)
