Aaron Davis finds the Iron Spider suit somewhere (sans chestplate) and repurposes it, especially the voice distortion feature. Did you notice in Homecoming, Peter used interrogation mode to speak with Prowler, who has a voice distorting mask in the Spider-Verse films? Presumably, the Iron Spider can also do this. In the comics, Aaron Davis got an Iron Spider suit on the black market, so maybe Kingpin's people who salvaged stuff from Avengers compound discovered the Iron Spider as well, and Aaron and Mac Gargan could purchase it together. They would take it apart, use the tech to build their suits. The scorpion tail would be a Doc Oak tentacle (the schematics for the tentacles would be saved on the suit's computer) with the tip of one of the spider legs for the sharp point. Meanwhile, Roderick Kingsley would discover the smashed Green Goblin Mask in the alley, and buy the Goblin Glider from Kingpin's people, and paint both orange to become hobgoblin. Kingpin himself could also still be alive, or perhaps Richard Fisk could take his place? Is he alive? Was he in Daredevil? I haven't seen Daredevil.
Also, an interesting idea that probably won't happen:
The High Evolutionary Escapes K.N.O.W.H.E.R.E., arrives on Earth, and takes on the codename Jackal. In fact, seeing as the High Evolutionary has visited Earth before, and knows a good deal about Earth culture, seeing how Earth-like Counter-Earth was, perhaps he posed as a human, taking on aliases such as Herbert Wyndham (his real name in the comics) and Miles Warren (Peter's former biology teacher in the comics, who became the genetic engineering villain Jackal) For all we know, he could have taught biology while posing as an Earthling, and might know about Spider-Man. He could clone Spider-Man, creating Scarlet Spider, and name him Ben Reilly because he can't remember the name Peter Parker.
