I feel like this is quite similar to how De Zerbi sets his teams up.
The two central midfielders still come deep in build up despite not being in DM strata, whilst DLF and false 9 also drop quite deep.
Both IWs have instructions to stay wider and roam from position, false 9 has instructions to move into channels and roam from position, rest of team have no individual instructions.
I have tried the same shape with pure wingers on attack but they don't seem to push up as far as inverted wingers do, also pure wingers cross the ball way too much for my liking.
The IWBs stay wide in build up and then invert to create the three in midfield with the mezzala pushing up.
