I am definitely thinking about it. I just haven't settled on anything because we'll have to see how it can be implemented/will fit with the narrative going forward. It's mainly an issue of logistically inserting it.
What we discussed among ourselves is that if we do go ahead with the idea then therapy should be inserted into the main story (not an R&D project off to the side) and the narrative should not show what happens during the therapy sessions — it's Asterion's private time, of course. But that's all still undecided, it'll be a while before we're in a position to say for sure what we're gonna do.
I do think it would be neat if Robert recommended a demon therapist from his home realm to Asterion. I think that would be very in-character for Robert, he's the sort of galaxy brain hyper dimensional entity who goes to therapy himself as a prophylactic mental health measure. He's that one guy who says "there's nothing wrong with going to therapy, I have one session every other week" whenever someone talks shit about psychologists. And a mythical therapist, particularly one from an afterlife realm, would be better equipped to discuss Asterion's trauma.
