The thing about Norman is, he doesn't have to be a main spider-man villian. Introduce him in a Spidey movie? Sure. But FFH made it clear that there is a void left by Tony Stark and it's not just hero's looking to fill it, something he actually did in the comics.
You see they've already laid it out that someone copped the old Avengers tower...who got money long enough for that? Now that Tony is dead, setting up an Iron Patriot/Thunderbolts/Dark Avengers storyline in the aftermath of the OG's not being in play sounds awesome and reaches further than being confined to the spider-verse.
I would say flip the script and have him try to be the new Ironman, have him establish his own Avengers that eventually leads to the formation of the New Avengers (which is what Black Widow's movie will probably kick off) and once they hand him that L and strip him of his tech, he resorts to chemical means of enhancement.
