Thinking much less about The Infatuations but enough still to imagine re-writes that would tinker with the telling much more drastically.  Take out all or most of the literary gameishness.  Take out even Macbeth or maybe especially Macbeth.  Marías makes fun of writers who fill their books with historical info or local detail but his mode of referencing other literary works is just as pretentious at least potentially so, and just as filler-like in some ways.  Think of how Knausgaard would “translate” Marías’s story into something that fits into his narrative or novel.
