Oh man I LOVE Oracles! I love solo-playable games. I think it make stuff so much more accessible. Generally I love the social aspect of RPGS but I enjoy Ex Novo as a creative tool all by myself. And I think oracles for goblin errands sounds like a SUPERB idea! It's the kind of idea where I go: I should have thought of that!
I can only encourage you to work on them. Happy to help in any way if I can.
If you missed the streams - I started working on a warlock-inspired player class about the power of friendship :D
