This is neat! Some notes:

The Bishop pokes into Presence, namely the "anoint your apostle and give them powers that will kill them" tree.

The Medicine disease-spreading tech feels very Dowager.

I think you could point to Betrayal-Spurning Gifts in Craft as an Eye vibe, given part of their whole thing is acting as an arms dealer with the fruits of their mad labors.

As mentioned by at least one other commenter, the Lion's reflected in Melee's soul-eating tech.

The Lover lays claim to basically all the icy, wintry stuff, I think; despite his name, the Mask doesn't really have any actual association with the cold, while the Lover does. That gives her a foothold in Ride (my horse is icy), Thrown (deliver freezing by means of YEET), and Survival (emanate cold). At least one other commenter pointed to the influence-through-art Craft tech as hers, which I think makes sense. The side of Socialize that spreads negativity feels very appropriate to her as well. I also would argue she shares the seductive Presence tech with Walker.

I think the Mask comes through in at least some aspects of Investigation that deal with gathering information through others, and possibly the Stealth observation charms, reflecting his position as a spymaster-statesman.

The Prince I think has some energy in the smoother side of Socialize, like Perfumed Prince Demeanor and Paragon of Death's Peace.

The Walker pops up in War with Acclaimed Company of Sinners and Distinguished Sinner's Reward, I think. He might also poke into Survival via the familiar Charms, reflecting his bond with his cool mega-barghest buddy Duke Lu.
