This idea is problematic to me because it totally erases and in fact debases the twins' comic book origin as the children of Jewish and Romany parents, two ethnic groups that were exterminated as part of the Nazis' "Final Solution." altering their origin so that they are not only not the children of a Romany mother and Jewish father but are in fact the products of eugenics experiments conducted by an arch Nazi with a racist and genocidal philosophy is morally repugnant. It would be akin to adapting a book with Jewish characters and transforming them into neo-nazi skinheads on screen.
Making Wanda and Pietro mere pawns of Strucker's would be far preferable to turning them into a creation of Nazi/HYDRA eugenics. Because of course everyone knows that the Nazi's devotion to eugenics was used to justify their extermination of millions of
Untermenschen, including Jews, Romany people, the disabled, gays and the mentally ill. Strucker would never adopt children of such an undesirable ancestry but he definitely would enslave them, torment them and use them as weapons, exactly as Magneto did when Wanda & Pietro first appeared in the comics. This would leave the Maximoffs' ethnic heritage intact instead of changing it in the most objectionable way imaginable.
