perhaps you could have Chrono on the verge of stepping into a Time Gate, with his cat in place of the Fool's dog.
I really like this! It would work quite perfectly terms of both the picture and symbolism.
I'm still a little torn about the Magician. Bekkler works, of course, and I'd like to fit him into a suit card at least since he's a great character, but my preference would be for the trump to be taken up by a more significant presence. I do think Crono could function nicely, but I admit that aesthetically it's a stretch.
Chrono & Marle: Lovers (maybe Chrono as the Fool also?)
Lucca: Sun
Frog: Justice
Robo: Hanged Man?
Ayla: Strength
and Magus: Devil is a given, since he's also an NPC.
We seem to agree on these choices! I admit that I'm especially attached to Ayla as Strength -- aside from the obvious correlations, the image of her with a beast would be especially fitting -- and Robo as the Hanged Man, for these reasons.
- The Hanged Man has connotations of traitorship. This fits Robo's relationship with Mother Brain and the other robots.
- The Hanged Man is also in a strange, inverted position due to his desire to seek knowledge. This fits his relationship with humans: he doesn't fit in, but is eager to learn about them. He willingly chose that role, as the Hanged Man does.
- Robo selflessly helps cultivate Fiona's Forest and in the process, gains mystical knowledge, evidenced by the Entity conversation. That's very Hanged Man, to me.
- There's also the possible meaning of sacrifice, which aligns with Robo's identification with Prometheus and his later sacrifice in Cross.
- Robo is a badass and so is Odin. (This is the least effective of my arguments, I confess.
)
All in all I like how there is something tragic and selfless about the Hanged Man, and how that speaks to Robo's willingness to go into the uncertain future, and of course his eventual demise by way of FATE.
All of these, save the traitorship aspect, also fit Gaspar, however. I am not entirely sold on the appropriateness of the Hierophant to Belthasar: the role definitely fits the one Belthasar filled in Zeal, and the one he fills in Cross, but the most striking image we get of Belthasar is definitely as a solitary madman. Still, I feel that Belthasar could fit as the Hierophant regardless, and if we made Robo the Hanged Man we'd have to figure out where Gaspar fits.
And Magus as the Devil is a given, for me. Too perfect. I also liked the fact that Lucca gains her best equipment through the Sun Stone; there's an added little detail.

I agree with your options regarding the Moon card. I chose the Black Dream myself because the meaning fit (as you described) and because in terms of the Trumps as the Fool's Journey, the Moon is often perceived to fulfill a "dark night of the soul" sort of function -- the period of illusions and terrors, the "valley of the shadow of death" where the Fool must traverse before reaching the Sun. I feel that the Black Dream
may color the card a touch negatively, so I've no quarrel with either that choice or Dreamstone.
That's similar to the reasons I placed Lavos as Judgment, because aside from the obvious apocalyptic associations (which are traditional depictions of the card), having Lavos next to the end of the suit striked me as very appropriate, since you would encounter it just before countering the Entity-Nu-World trump. But again, Death fits Lavos extremely well, and it could swap places with the Chrono Trigger with no problems.
Regarding the Star, again, your reasoning for the Pendant is quite solid. Since Marle is the carrier of the pendant, though, I feel as though a combination of our two ideas may be possible -- especially since Marle acts as the impetus for the journey to begin, and is a symbol of faith and hope when Crono dies, and since the card is traditionally depicted with a woman anyway.
