Not sure if 'setup' is the right word, but I found that ending the 1-bar corner combos in DB2 leaves you at the perfect distance for a mid-lunge crossup or an IA pounce. Wakeup backdash can beat the pounce but not the lunge, and an antiair can beat the lunge but not all will beat the pounce (some still do), so the version you'll lean towards depends on the opponent's habits.
Combo into lunge:
112xDB2, D1xDB1MB, B3, dash forward, 112xDB2, mid-lunge, JI1, B2xDBF1
Combo into IA pounce:
112xDB2, D1xDB1MB, B3, dash forward, 112xDB2, Instant Air DB2MB, JI1, 112xDBF1
