They're adding all these new characters but I'm just going to play with Ghost Rider and Blade (maybe Nico)
Not in the game. There are rumors that Hulk might be playable, but I doubt will see Dr. Voodoo unless he's introduced in the MCU and then added in DLC
Every character outside of the Hunter (customizable player character) has a live action appearance under their belts. Moon Knight, Man-Thing and Werewolf by Night have better chances. Heck even Hellstrom and Satana from the Hulu show.
Don't get me wrong I'd love to see him in the game but looking at the other characters they've added it feels like a loooooooong shot
