How to force Osborn into the MCU

Allegedly, Sony will add Norman Osborn to the Spider-Man movies. There's some rumor that at the end of Far From Home in a post credit scene Ann Osborne associate will begin Gathering villains for the new Sinister Six. Shocker, Vulture, Mysterio, and (rumored) Chameleon will be part of this team and the leader, Osborn has bought Stark Tower.

Personally I find this stupid. While  Norman is a giant douche he shouldn't start as THE Villain. I would have him as a philanthropist and businessman who sees an opportunity in the wake of the end of many Avengers. He buys start start in order to reverse engineer some of Iron Man's tech...  since  some of Stark's technology is part of the actual building it makes sense that some of it was left behind. While his companies working to improve the life of New York and their citizens; Norman is secretly trying to remake The Avengers In His Image.

 Through illegal means he obtains  genetic samples from certain Avengers: Hulk, Cap, and Black Panther come to mind. Somehow he is able to create a serum that combines the abilities of all three. In a fit of rage, Harry, Norman's son, hacks the data on the new Super Soldier serum and increases the Gamma Radiation needed to an unsafe range.

Norman tests the formula on himself, loses control, Hulks out, causes a massive explosion on Osborn tower killing many, and wounding an Otto Octavius from the Tech division. Norman learns to control his Hulk form rather easily (it's not Ultimate Goblin big... Think of it closer to Scrawny Steve Rogers became Chris Evans buff, but Gamma green, more goblin-looking with flowing purple hair.) and decides to use his Goblin persona to eliminate the competition (the Avengers) to pave the way for his Private Superhuman Military Company, The Thunderbolts. Norman chooses to test his abilities against the youngest Avenger, Spider-Man.

To tackle the design, I'd to go for a more traditional Goblin inspiration even if it's based on Ultimate Goblin. The long flowing hair that I mentioned earlier is a compromise to get the goblin cap look without having it be a Goblin cap. His main outfit would be a sort of special compression undergarment, that can resist the effects of the transformation without tearing Norman's clothes off.
Made from a reverse engineered piece of Black Panther's kinetic armor, it can absorb kinetic energy, which can be released as stun blasts, or fireballs that resemble flaming jack o' lanterns while in his hands.

The Glider is a modified set of Vulture wings with holographic projectors that make it look like a bat out of Hell.  (Possibly Mysterio tech)

Norman's personality: I already mentioned that he's a douche. Think of him as a much, MUCH less likable twisted version of Tony Stark. He has an axe to grind with Stark Industries, SHIELD, and others. Heck, I would've established Norman like this:

Oscorp unveiling their new HQ at the former Avengers tower,  where Norman is making a speech about Oscorp becoming a new beacon of hope for humanity, to which a reporter asks if he's trying to be the next Tony Stark...
Norman replies:
"I'll be the FIRST me, not the next Tony Stark, thank you VEEEERY Much!" In order to establish his massive douchiness.

Once he becomes the Goblin, he would create a threat that his Thunderbolts can stop in order to fleece cities... trying to consolidate power as both Norman and The Goblin.
