If the Defenders, Punisher, Runaways, Inhumans and Agents of SHIELD did appear in Infinity War, what would their roles be?

The movie takes place over the course of two or three days. Way I see it, the characters are where they're at because they know people (in the case of Steve and the others in Wakanda) or by chance (in the case of Peter, Tony, and Strange). Like you had to know Steve to go to Wakanda and only the people that came with Steve would be in Wakanda

Also, I don't think any of them would've ended up on Titan with the Guardians and the others. The Guardians were only there because Nebula had told them and that's where the ship took Stark, Peter, and Strange. Hence, the only place for any characters to be at was Wakanda.

But I digress.

1. Runaways: They'd be sent home. They're kids, they have no training, they'd be in the way. (Yes, Peter is also a kid with little training, but Tony tried sending him home and Peter snuck abroad anyways. He put himself in a position where going home was no longer an option.)
2. The Defenders: I think they'd realize this is above their pay grade and stay in New York. Remember, even the most skilled fighters in the MCU (Cap, T'Challa, Bucky, Okoye, and Natasha) were having trouble against the Children of Thanos and those dog looking aliens. The Defenders wouldn't last long.
3. Ditto with The Punisher: Anyways, who knows what the situation in New York is like after Ebony Maw's attack and Stark’s gone missing. The Defenders and Castle may be needed there to keep the peace. thea queen cosplay
4. Agents of SHIELDS: Hell yeah, they'd be in Wakanda fighting alongside Captain America and the Avengers. Especially the Secret Warriors. They're all skilled fighters with experience fighting aliens. (I actually had a hope that they'd show up mid battle and kick ass. But Thor showed up instead (not that I'm complaining lmao))
5. Ditto with the Inhumans: I imagine that if the Inhumans were there, there'd be more people guarding Vision instead of some palace guards and Dora Milaje. But this hinges on the Inhumans knowing Steve and/or gaining access to Wakanda. red arrow costumes
