You can try turning down the wattage some and increasing airflow, yes. That may or may NOT improve your experience, as you'd only be able to turn it down to a certain point, after that the vape may become weak and anemic.
I would consider another setup as well. If you are chain vaping in wattage mode at relatively high power, you are going to overheat your juice.
You may enjoy a more airy mouth to lung experience, either the original crown Uwell tank that has a great deal of variety of coils to try, including a 1.2 ohm coil, I think.
You could also try something like the Innoken Zenith tank with the 0.8 coil. It seems to me you may want a vape something in between subohm and MTL, so you could also look at setups that have coils in the 0.5 range, maybe a Vaperesso tank with the EUC coils, they offer a 0.5 resistance coil that's quite pleasant. I'm rather MTL but I can vape that coil. I do know my limits though, I showed up here with a regular Cleto tank, and it was WAY too much vape for me, and I don't think I'll ever venture far past 0.5.
The good news is, you need a backup tank anyway, really a backup setup. It should give you the chance to rotate your vapes so they don't overheat, and you may also find the vape more satisfying. It's different, certainly, any change is going to give you a different vape, but I kind of have a hunch that coils in the 0.8--0.5 range may give you what you are looking for. But, it's a hunch, and you may well find turning down your wattage 10 watts and opening the airflow is enough.
If that is not enough, it's time to explore some different setups, I'd think. Best of luck,
