As much as I agree, Bloom has no history with Cora, and it doesn't fit the narrative of seeking a clean break from the Dombrowski era. If Cora does come back as soon as '21, it would be have to be an edict from above -- remember the owners' outpouring of love when they agreed to part ways. But since '21 will most likely be a rebuilding bridge, it would make sense they'd let Bloom bring in his own people.
However, Bloom wasn't hired to get rid of Cora (like Price and Betts), so when/if ticket sales and interest compel ownership to start splurging again on star power, don't be surprised if Cora is part of the recruitment drive.
