Good question and TBH I'm not sure, but my stance on the solar stuff if that its so cutting-edge and such frontier science that your guesstimate is as good as mine.
However, what I do feel more confident in is that Modoki la nina are positively correlated to both flatter Aleutian ridge and +NAO.
There are 8 modoki la nina events of various intensities in my composite of all seasons dating back to 1950, and of those 8 seasons, 2000-2001 is the only one that averaged a DM -NAO in the mean...and it took a supernova SSW and resultant month of March to accomplish said feat.
In addition to 2000-2001, 2008-2009 is another viable and potentially favorable type of outcome, which also featured a DM +NAO in the mean....so that isn't a death knell for us like it is further south.
