Creator here. Yup, in fact you can check out something like that here https://github.com/SelectTransform/JSONQL

Basically you can send the JSON template over JSON to the server, and let the server transform the raw data using the template before returning.

The most important benefit here is that, since everything can be expressed in JSON, it can be stored or transmitted over the Internet, which enables interesting cases like this.
