Craig from Citus here. From our cursory looks it does look like they could work together, though personally we've not tried it and I'm not aware of users that have (though it's entirely plausible some have already). What you'd have to do is setup timescale on each of your distributed nodes and tables. You'd still talk to Citus as the primary point and it would re-write and push the queries down to the nodes which could then leverage timescale.
