Another along similar lines as GOTHAM BY GASLIGHT was WONDER WOMAN: AMAZONIA (1997), that set Wonder Woman in the late 1800's with a clear Victorian era flavor.
By William Messner-Loebs and Phil Winslade.

This was the first art I'd ever seen of Phil Winslade's and I was quite impressed with the ornate steel engraving art style, representative of pen and ink art published in that era, such as Gustave Dore, or what Wrightson attempted to capture in his illustrated version of Mary Wollstonecraft Shelley's FRANKENSTEIN novel.

WONDER WOMAN: AMAZONIA is also in a larger 8 X 11" magazine size that allows you to better appreciate the art. I can't offhand recall any other Elseworlds published in that size.
