I did some more work on the chronology, and I settled on this structure:

TPOWW -> APFP -> EFAFV
                     \
                     MWBW -> WTDGLAH -> (Future Story Arc)
                     /                              \
        [tbd] -> [tbd] -> [tbd] ----------> RHHM -> SDJD

Everything on the bottommost row is part of the second writing cluster. The [tbd] writings are plot holes to be filled in by future writings.
