Oh my, that has all kinds of terrible connotations that could go very wrong, especially as we know Marvel's stance on Odin and that goddamn "worthiness".
Thor began to grow wonderfully as a character when he started seeing the cracks in Odin's exterior and realized how wrong and flawed his father was. When he started seeing beyond Asgard's lies and bigotry. The entire point of his character was supposed to be a boy indoctrinated from childhood finally breaking free from his father's lies and control, which necessarily translates into that "worthiness" meaning nothing.
We got Hela's story in Ragnarok! She was told she was worthy too. It was all a lie, even Valkyrie says as much. So a book where Loki is worthy and it is supposed to be a good and positive thing is missing the point entirely. It's still taking Odin's judgment as gospel.
With that said... damn, a story such as that written by a Loki fan could be pretty amazing. Imagine a story where Loki was treated the same as Thor and had everything he could possibly want, he was respected by his people, etc... but it still went wrong because all that love and "worthiness" were corrupted from the beginning. A story where 'who' and 'what' Loki is turns out to be the only good thing... but Asgard's bigotry and Odin's lies and crimes end up biting them in the ass in the end - and Loki's worth comes from within instead.
That I would read. But something tells me Marvel will take a different route. Oh well. (Also... Loki and Valkyrie, eh? They gonna pair them up? 😜).
Gotta say the other two books sound interesting though. Poor Marc having to put up with Venom, but he has experience with Khonshu being a lovable jerk so he'd survive it, I'm sure. But Wanda and Peter as siblings? Hell yeah gimme!
