Despite Jessica and White Tiger crossing over in HEROES FOR HIRE, I don't think I picked up on the detail that Tiger had picked up Jessica as a evolved spider's origin story.
From the description of the "THE ANTI-ARACH-9", they sound like they are rogues introduced during Pacheco's run, so that pares down the potential members... https://www.previewsworld.com/Catalog/JAN220907
Pulling from beyond that, my fan-fic spider rogues would be more along the lines of :
DEATHWEB: Anthro, Arachne, Therak (Julia Carpenter villains introduced in AVENGERS WEST COAST
SPIDER WOMAN: Charlotte Witter
DOCTOR OCTOPUS II/LADY OCTOPUS
TARANTULA - one of em, Maria Vasquez never seemed far from a turn to the dark side.
