It's been suggested before... and it may well prove the case for the Tyne-Wear outfits.
Relegation is and would be a disaster for any Premier League team. Obviously.
The amount of TV money now available to top-flight sides is well documented and losing your Premier League status is guaranteed to make a huge impact.
But, for some, the dreaded outcome could end up a blessing in disguise in the long term.
Naturally, that points us to Newcastle United and Sunderland, the local rivals who have been skating by without putting enough effort in as clubs or ploughing enough resources in to truly compete for years.
How Sunderland remain in the top flight to this day is a sheer mystery and, under Sam Allardyce, they may well achieve that feat again. But what happens when Big Sam leaves - which will likely be after a short-term stint?
At Newcastle, the same issue exists. Under-funding and a general misallocation of resources have plagued the Magpies for years. The fans weren't happy with Alan Pardew so Mike Ashley gave them John Carver and now Steve McClaren.
Maybe both clubs need Championship football to remind them that a lack of progress each season will generally see you fall down the pecking order?
It would serve as a kick to both boards and, hopefully, set a long-term strategy in motion that would see both clubs compete in the Premier League - properly.
Newcastle have been relegated, of course, and it didn't necessarily see any changes in approach. A second relegation in the space of a few years would send a clear message to Ashley and co, though. And Sunderland going down would certainly do the club plenty of good and allow for an extensive shakeup.
