I haven't yet tried "Quescussions" as they are described in the article, but I think the general spirit of asking students a set of structured questions, followed by reflections on group answers, is very much in tune with LAMS.
An advantage of LAMS for the Quescussion process is that authors have several different tools that fit this format - obviously Q&A, but also voting could be used along these lines, together with both Chat and Forum for more extended questionning. I think a structured sequence of questions that uses different tools from time to time would help to keep the topic "fresh" for students, and avoid a sense of repitition that might arise if there are many questions and only one type of tool to ask them.
