I will have its grounds that I didn't remember and had to review it. It's complicated. She states that the assumption of such an empire - which is done by the majority of scholars - is based on 6 reasons and then she elaborates in detail why she considers these reasons not correct or at least not enough supportive for such an assumption.

The main direction seems to be that she considers Gregory of Tours simply wrong in some points regarding the time that he didn't experience himself (he also reports that the Franks hailed from Pannonia) and that Thuringia politically streched till the Rhine river and a number occurances assumed on the left Rhine side were in fact on the right Rhine side.

The 41 pages article Gab es vor 531 ein linksniederrheinisches Thüringerreich? is in German and available here:

It's very interesting and worth reading in any case considering how many subjects it touches. Maybe you have the possibility of an automated translation.
