Technically, we can already grab Chaos stuff? The Tide of Skjold have the Theological (Chaos) specialty. As Norscan pirates who were rejected by the Chaos gods, they'd make an ideal choice to go beat up some other Norscans, steal their (un)holy totems, and bring them back for us to put on display. That's not quite the same as raiding the Realms of Chaos themselves, but it's possible that we might be able to send them on a mission that audacious. That's not the same as expecting them to return soon, safely, or at all from such a mission, of course, nor is it a guarantee of satisfaction for the results of such a mission, but it might be an interesting thing to try at some point. Note that it might take a while for them to be available again, since the current leading plan has the Tide sailing to Mousillon to do piracy, which will keep them busy until the year after next.
Granted, there's a difference between a Chaos Acquisitionist, and a Staff Daemonologist. Having a Daemonologist on Staff is the part that makes it somewhat approximately safeish for us to start grabbing Chaos stuff to put on display, since they'll have better ideas for how to keep the cursed things from escaping containment and causing trouble, and for how to respond if they start doing that anyways. Do recall that we had the option to employ two different Daemonologists earlier this turn. We turned it down, but since they were both Pahtsekhen's former students, it's not at all implausible that we might see them again. In fact, the runner-up from that vote was Bahr the Betrayer, and Boney auto-included the previous runner-up in the last staff vote, so it's nigh-guaranteed that we haven't seen the last of Bahr.
If you're primarily interested in grabbing Chaos loot, note that any of the votes that earn us a Goodwill will give us the option to take another shot at hiring Bahr (and/or a different Daemonologist). That said, since the top four vote options all do New Audience, that part is pretty much guaranteed to happen. Open question whether the thread will be interested in a New Staff pick for the second year in a row, though. Also, consider voting for Plan: Lustrian Magic, since it doesn't keep the Tide busy, which will at least make it possible for you to suggest sending them out to steal Chaos things next year.
