1. Definitely! Steve's not attached to Gloucester in particular, especially after just arriving, so there's no reason I can think of that he wouldn't be willing to leave.
2. Steve is a good strategist and could be helpful in situations that require planning and resource allocation. He is used to dealing with frightened people, although he's not a huge fan of lying and obfuscation, so he may be more helpful with general in-the-moment crowd control-type situations. He has super strength/speed/endurance and access to a potentially powerful weapon (Mjolnir), although he has not yet tried to access his power via feeding an entity (the Slaughter). This could be a situation that tips that mental balance, however, or his willpower could end up eroded after he's been in this world long enough for him to start getting restless/rowdy and end up feeding the Slaughter unintentionally. I'm definitely willing to entertain one or both possibilities! In general, even without his powers he's a relatively large/strong human with combat experience and could be helpful in protecting innocents/bystanders and putting a stop to nefarious activities (rituals). He's definitely better as a visible piece of any solution (i.e., he's not great at spying/staying under the radar without some help), but he is willing to become a public face for helpful efforts if needed.
