I haven't looked into Alone on Silver Wings, but I've read through Undying and I'm a fan of quite a bit of what it does! It's neat, and kinda feels like someone took Urban Shadows and added even more World of Darkness flavor and elements into it. I think it definitely doesn't drift too far away from the core elements of what most people think of as Powered by the Apocalypse games, though, and while it adds things it doesn't take away much. There's a GM, there are basic moves, there are debts that tie characters together that they can use on one another, there are playbooks that all have playbook moves -- even the Status Moves and status feels a little like an alternative to Corruption. It definitely adds in some awesome new things, but I can see why it calls itself a PbtA, since it sticks very close to the recognizable framework as well.

(I also think this way about City of Mist, which takes out playbook moves entirely, takes out stats and changes how statuses work, and adds in the tags system, which I absolutely love, and has you build your own character out of choosing multiple playbooks and combining them, which is just a super neat concept to me. It's still got so much of the Powered by the Apocalypse that it's still very recognizable as such, imo, even despite the pretty extensive changes it makes! So this can also obviously be pretty subjective and depend entirely on the individual game and the person "judging" whether it fits the framework enough or not.)

As it is, I think both your game ideas still stay really close to the Belonging Outside Belonging framework! From what you're saying, one adds a slight change to what tokens can do by adding in one more thing they can do? And the other adds in dice only during certain moments but otherwise goes back to the "standard" BoB gameplay. Of course, you're talking specifically about working on these for the game jam and the guy running it talked about staying as close to the basic framework as possible (in which case I'd say your vampire one might indeed be more suitable for the jam), but that's more "what this specific jam is looking for" and less "what would be fair to still call Belonging Outside Belonging." The latter might be wider than the former for any given jam.
