Chrono Trigger/Cross in the same vain of Black Isle Studio Games, e.g. Fallout, Torment
A Chronout/Falloss would probably work as Fallout was post-apocolyptic...so it would have to be set in the ruined 2300ad future of Chrono.
Tormented Chrono would be probably best fit in a dirty 600ad era or post-2300ad, when humanity starts up again.
I would pay for a Chrono game in that style, for sure.
