Having overthought this too much, I will share my results.
On the subject of multiclass investigators (investigators with deckbuilding options of 0-5XP Class A & 0-2XP Class B), we've seen 9 so far.
Guardian|Seeker: Roland Banks
Seeker|Guardian: N/A
Seeker|Rogue: N/A
Rogue|Seeker: N/A
Rogue|Mystic: Sefina Rousseau
Mystic|Rogue: N/A
Mystic|Survivor: Agnes Baker
Survivor|Mystic: N/A
Survivor|Guardian: William Yorick
Guardian|Survivor: N/A
Guardian|Rogue: Leo Anderson
Rogue|Guardian: "Skids" O'Toole
Rogue|Survivor: N/A
Survivor|Rogue: Wendy Adams
Survivor|Seeker: N/A
Seeker|Survivor: Mihn Thi Phan
Seeker|Mystic: Daisy Walker
Mystic|Seeker: N/A
Mystic|Guardian: N/A
Guardian|Mystic: N/A
I wasn't expecting them to do both Multiclass A|B & B|A, however Leo & "Skids" mirror each other. Ignoring that, we're missing a Rogue-Seeker and a Mystic-Guardian mash-up.
I'm not really expecting them to cookie-cutter 20 of the 55 investigators so that we have all possibilities, just thought I'd bring my findings to the discussion table.
