Two things only I would lightly disagree on.
First is Selune's chosen. That can actually be a great item if you use it on elves/half elves. Since it's a cantrip you can cast it over and over. Can be a nice method to heal out of combat if you are out of or don't want to burn a short rest or potions. Also if you use it with the healer items that grant temporary hitpoints on heal you can buff your squad out with a little extra beef before starting a combat encounter. As a combat item though I would agree, it's not great. Better to just use a potion or healing spell as a bonus action in combat since Selune's dream counts as a full action.
Second would be circlet of blasting. This has a niche on warlocks with Hex or anyone who take warlock initiate and gets Hex. Multi-hit spells like scorching ray are made crazy strong by the extra damage procs from each hit. Using the circlet on a warlock lets you launch a super damaging attack without sacrificing a lvl 2 spell slot to do it with a normal scorching ray. So it isn't entirely useless. I certainly wouldn't be upset if it got a rework on it as your suggestions would give it a more mainstream use.
You did well to say it, I did not know that Selune chosen had become a cantrip (It may not be so bad after all).
For circlet of blasting it is indeed interesting from this point of view, even if eldritch blast gives multi hit on target as a cantrip (1D10 eldricht blast + 5 agonizing blast + 1D6 Hex ) * 2 because Lv 5 Eldricht blast.
Lotus noctus : If only it were possible lol, and at some point gayle told us: I can't stand it anymore... I'm going to get indigestion, I'd rather explode than eat more.
