I am willing to bet that if we were to ditch the gap between the RONI and ONI, or even have the ONI lag the RONI, we would get lower heights in the southeast....my guess is in order achieve that we are going continue to have to see that western Pac warmth spread eastward, which would help to reduce that persistent, residual cool ENSO residue. Again, don't mistake me overvaluing the RONI in-and-of-itself....it's what it represents, which is the surplus of western Pacific warmth relative to the eastern Pacific reducing the ability of +ENSO to couple with the atmosphere, and thus modulate the northern Pacific in the manner that we would like.
