If Marc got Bruce's blood he would be killed, because Jen and Bruce are family and Jen's blood can hold the lethal amount of radioactivity in Bruce's blood, but Marc couldn't. Jen being Moon Knight could work out fantastic!

Jen would just make a case against Khonshu for holding someone under duress.

@SpiderFan2104 this swap would have Jen as She-Hulk & Marc still as Moon Knight in both series. Like for example how would Moon Knight battle Titania, while how would She-Hulk battle Harrow?

Okay essentially if they swapped locations really.

I mean Marc would probably be initially confused in believing that one of his many alters is a lawyer named Jen Walters, but probably would still be able to beat Titania due to the mystical augments that Moon Knight has in this series. And be screwed as a lawyer for afterwards for all alters involved.

For Jen, there's the initial confusion of what to do given that most of even getting to Harrow involved Marc's resources and Khonshu's direction while Steven was asleep. Though when it's all public and he's sucking all the souls up for Ammit's judgement, she'd probably attempt to beat him. However due to her super strength not really being enough compared to full on divine empowerment given the close calls Hulk has previously had with Thor, she'd break the fourth wall just to correct the swap in the first place.

@Louis' Adventures Oh than it can easily happen

Yep, through psudo divine intervention. Yeah, what Xandermcc said sounds about right.

Well that would be interesting.

I think it would be funny to see how Jennifer would react to those situations. Plus her seeing gods might have been an interaction,

I feel that her friendship with Taweret would be good. And Layla and her could have been good friends

As for Moon Knight that would have been really different. Now Steven might have a normal reaction to a lot of the events. Him seeing Wong would have been interesting. Not sure how he would have reacted to Abomination. As for the others probably calm reactions. Steven and Titania interactions would have been interesting. Probably the best thing for this switch up would be Moon Knight and Daredevil teaming up that would have been really awesome

Like how Ms. Marvel and Captain Marvel switched places?

@JMATIUAS more like replace one character with another like replace Marc with Jen and have her fight Arthur & his cult in Marc's place as She-Hulk, while Marc takes Jen's place but not as a lawyer, but rather the super hero as Moon Knight and fight her enemies.

Marc's not a lawyer.... Jen doesn't have traumatic past to create Steven (or whoever she would make) also other reasons
