I don't want to see all of them relegated at the same time. I'll be happy if they go down one by one.

Inter relegated. The next year Inter returns and Roma are relegated. Then Roma returns and Fiorentina are relegated.
Then Fiorentina returns and Milan get relegated.
Then Milan stay in serie B forever and ever.
Of course, all of them will lose hundreds and hundreds of millions due to the relegation and we get to buy their best players with 50% discount.
