A Longer Technic History?

As Nicholas van Rijn cameos in the first trader team story, Dominic Flandry cameos in what could have been the first in a series of novels about Flandry's daughter, Diana Crowfeather, if Poul Anderson had not instead begun to write a different kind of future history series with opposite presuppositions: AI, STL and no aliens. In the post-Flandry period of the Technic History:

one story about Roan Tom's achievements during the Long Night could have become a series;

two works about the Allied Planets re-civilizing isolated colonies could have become a longer series;

one story about discoveries made by a Ranger of the Commonalty could have become a series.

In fact, that last story represents a new beginning with human civilizations dispersed through several spiral arms of the galaxy and a new source of vast wealth about to be opened up. And there the series had to end. I would have appreciated a longer Technic History.
