I may not agree with all the particulars of this, but it shares my sentiment: he deserves to be up and playing every day.
I would have Arraez/Urshela splitting 1B, MIF stays put, OF stays put (Kep/Larnach/Buck), catcher stays put, and DH continues to be used as a way of keeping people in the lineup but giving them a rest.
That leaves 3B and he should play there if he feels comfortable there.
