The 2nd half 20 miles of it is done around the 11:00 am hour, when the temperature on these kind of days ranges around 80-90 degrees (while the other half is 2 am-cool), and about 8 miles of it is downhill. I know I read somewhere that some people seem to think that Nissan thinks 80 degrees is really super hot. Also, the car will be parked in the shade during the hottest part of the days So based on what I said in this paragraph, is it still your opinions that I will really be driving "in really hot conditions" (where a lizard pack will do me the most good)?
Based on experience with both the original battery in my 2012 Leaf (May '12 manufacture/Sept. titled) and a new "lizard" battery installed in Nov. '16, both batteries have degraded about the same rate of .47 amp-hrs per month overall* (note that this might not correlate directly with GIDS). My Leaf has been in the Houston TX area its entire life with 95+ temps common during all summer months from late May to late August. As you describe your driving, I would estimate you could likely use only 3.2 - 3.5 GIDS per mile (my best guess). IF GIDS correlate well to ahrs, you will likely lose about 2 GIDS per month. *There is another consideration however, and that is during the annual temp cycle, the ahrs tend to reduce (actually quite substantially) during the winter months. That might be the limiting commute for you - depends on how cold a winter. Obtaining a 120 VAC outlet at your workplace might resolve any degradation problem as you would not need too many additional GIDS to make it home - thus putting off buying a replacement battery. Note that at VLBW, there is about 20-25 GIDS remaining.
