It is the only reasonable direction to move it if you were to move it at all. Which you might not want to. Could doing this eliminate the minimal available crown of about 1mm that was measured? Possibly, probably? Out of the frying pan? The bearing condition is reflective more of the crown condition than anything else. Based on what you've said, it sounds as if this board is trying to die. Could an added response possibly be that the positive front bearing at the top treble part of the bridge would increase? It might marginally, but I can't really see how unless there is a drastic reshaping of the crown condition by decreasing that negative bearing.
