Just a thought: I feel like it's not fair to ask someone creative to be completely one and the same with another creative person. Aside from bearing the original name, she is not here. It's impossible for him to actually get to know her! He's a guy from Texas, she was European noblesse. They are nothing alike.
What you say I do get, but that's when extremely good fortune happens, it's the exception not the norm. And the demand for complete loyalty is stifling for creativity. A prime counter argument is John Galliano at Dior: let's not kid ourselves that we were all fawning over him because of his military reverence to the Dior's DNA. When a designer gets a job at a big house, that's a chance for that designer to make his/her mark. Are you not at least excited for the prospect of something new and of our time? Why do we have to make it so literal? Fashion history is just like fashion: utterly ephemeral and not a reliable source. We get fed a lot through the lens of fashion media and a lot of it is editorialized and crazy subjective/ often mindless. You see it especially clear now with social media, am I supposed to believe that everything is instantly legendary and iconic? There's no way we can really know the DNAs of Elsa Schiaparelli, 1) we weren't alive then 2) she was not well documented as a creative figure.
The excitement around this brand on IG and the amount of celebrities who look tacky in his garments might be the main reason that turns you off. I don't follow this house obsessively, but as someone who's close to a few daring and well-dressed women, I know taste is a matter of self understanding. If you have cultivated taste the garments often work for you. Farida Khelfa and Natalia Vodianova have been seen in his Schiaparelli a few times and both managed to look quite discreet. I also have seen many a client butchered their Chanel Couture to the point of tastelessness. 2 sides of the same coin.
P/S: have a hunch you already know
@jeanclaude about Michael Stewart, but if not you should check him out. His work has a strong Cristobal oeuvre from what I've seen.
