This is exactly how my LS handles outside triggers. You get one item of your choice after you see the loot pool, and we will distribute the rest via our rules. The only issue is our schedule, which rotates on a weekly basis. We do Sky/Sea/ZNM/Free Week + Alternate Events on a 4 week rotation, with Einherjar and Limbus being standard bi-weekly events.
Currently we are finishing Sky, so that means you would have to wait until the week of 1 June for doing your triggers to be a possibility. If you like what you see and are interested in working something out, you can /t any of: Danita, Keziiana, Daysitae, Lildant in game, or contact us via some alternate method. We've seen one harness in 6 Tinnins with TH4, just so you know.
Regardless of if you run with us or not, let me preemptively wish you the best of luck.
