Hi @rxunique Thanks for reaching out! Have you already moved forward with a solution? One approach is the JSON Schema Form, as you mentioned, because you can dynamically display components. I would also recommend trying a list view in a form 
For now, I'd use the legacy list view (for the reasons discussed here).
We generally don't have components that support end users drag & dropping to re-order, other than the re-orderable list component, which would be too simplistic for your use case. If this is necessary for your app, you could also consider spinning up your own custom React component
