Ask HN: Any academic efforts of writing new national democratic constitutions?

Some (most?) of the national democratic constitutions were written right after or during the periods of distress, and under some urgency, perhaps skipping some cool headed debate/discussions. Amendments to a constitution are supposed to correct issues with them and keep it up to date according to cultural shifts and scientific discoveries. But even then some aspects would be mediocre given the involved lobbying, trade-offs, vote-gathering etc. Are there any academic efforts of creating new democratic constitutions, which has gone through the rigor of peer reviews and validations against the known forms of inequalities, corruption, injustices, new techinical capabilities etc? Or is a constitution too context (read culture, mindset, economy) dependent or philosophical that such an effort won't be fruitful?
