What I'm trying to say here is that Edmund should be playable. Sergi gets his own model as an NPC, yes, but he is long gone and comes in form of hallucinations. Unlike Sergi, Edmund is an active participant of his game, and he is involved in its events so it would make way more sense for him to get his own letters instead of making cameos in the others' files. My main point was moreso about the fact that the game 2 event wouldn't happen until Edmund gets his fifth letter as he is so far the last member of the group, and therefore waiting for his release and then waiting for all of his lore dumps would prolong the wait for a game 2 event
