I'm aware of that, haha, I live nowadays right by the 60N latitude (Stockholm, Sweden) and came from Brazil at around 23S, I've experienced both types of sunsets and I'd say I find the ones at higher latitudes to be much more spectacular than the short ones closer to the equator.

So let's say a trip onboard a 787 around the +-60 latitude during spring/fall equinox is completely doable for chasing the sunset :)
