i did a very long highway trip on a very light single (<150Kg) and while i understand what you mean i really don't get how something like your adv that is just a bit heavier and has almost 20hp more than what i was riding could have such a problem with speed, the wind maybe but you are basically trading one slight annoying thing you only get on highway with a lot of wind with all the bonus of having a light bike.
You say you don't want a boring bike but getting a heavy two-cylinder bike that would fix your highway problems is probably going to make it even more boring and you get less fun when out of your highway commuting that is innately boring in the first place.
As the other anon said, maybe some more premium bikes can still be funbikes like the T7 or an old GS but you should probably try and see which one is a bit more "peppy" and still has some single vibes to it
