We could, and that's what the original v2 patch did.
However, this prevents package transformations:

  (package
    (inherit libosinfo)
    (native-inputs
      ;; not sure about the syntax 
      (modify-inputs (package-inputs libosinfo)
        (replace "hwdata:usb"
          hwdata-with-some-new-fancy-hardware "usb"))))
