Since the direct quote from Dershowitz is the key, the suggestion of an embedded decode requires the coordination between Dershowitz and someone from the Trump people. While Dershowitz defends Trump on the Special Council, in no way has he suggested that Clinton should be indicted. He was just on Hannity and he acknowledged upon prodding from Hannity that he agreed that any wrong doing should be investigating. He was not in front espousing additional investigation. Having listened to Dershowitz over a period of time, this coordination and intentionality is patently absurd.
The opportunity of the message is what should be considered. First of all, you need someone to find the opportunity of the wording as well as the desire to deliver the message. For that you need experts in coding that works with Trump and has shared this opportunity with him. We would all presume that this would be Q or someone that Q works with. Also these tweets would have to be prepared for Trump and instructions given on the 26 minutes. I suspect if this were so, the operative(s) would have posted the tweets with the President's permission. I would suspect that Q would post something about it even though this decode is on Steven W's post (and a few others in this overall thread). Note that Q does answer some Anons.
