I think the most significant change would be that we would be more likely to see some periods of poleward Aleutian ridging, but unless it were strong, the data doesn't show that it is a huge deal. As far as intensity....sure, a moderate peak is definitely plausible because its never really strayed far below that threshold, but again....I don't feel its a big deal unless it got closer to the strong threshold, which I do not expect.
I think basin wide could also alter the timing in that it would increase the odds of a favorable mid season stretch, and place less emphasis early on in the season, but that is kind of minute detail for this range.
