This type of system sounds similar to the one in Belgium and other low-rated leagues around Europe, which is fine for shit teams in poor leagues who don't go far in Europe and from March onwards everything gets boring and TV rights aswell as ratings drop, so altough i don't agree with it as it's dumb and basically makes the regular season not worth anything i understand why some might be needing this type of format, however when it comes to Seria A or any other top league it just won't be feasible because it would eventually only lead to confusion and it will complicate things even more for teams engaged in the late phases of UCL/EL.
