Interesting finding.
I was not aware that this has been a topic of academic research.

Description of the research book. Note the mentioning of the Gospel of Thomas:
"The Critical Edition of Q offers for the first time a collaborative reconstruction of one of the most important documents of the early Jesus movement, a written collection of sayings and stories antedating Matthew and Luke and at least as early as Mark. It is laid out in the form of a Synopsis including the Gospels of Matthew and Luke, Mark and Thomas with English, German, and French Translations. All this material, put on parallel lines side by side in eight columns, makes it easy to follow the Q text down the page between the texts of Matthew and Luke that made use of it, and even with parallel texts from other early Christian literature. It is intended to be a standard reference work, on the desk of every student of the New Testament."
