I really like the idea of interdiscipline teams.
Combining at least one developer with domain experts from different backgrounds would make sure both parties can contribute.
Using vibe coding techniques where the domain experts create a naive implementation and the developer can guide them into best practises (and help when the model capacities come to their bounderies).
And I also agree that the general idea might be a little bit too much for a weekend hackathon.
A single part of that on the other hand would be perfect.
