Aww thank you so much ^w^
I love the bond they have and am glad that is still a thing in the new era. However, it's apparent that they're adopted siblings (since Bi-Han+Kuai's dad technically took Smoke in as his own.) Because of that, I feel this time around they are too much like actual brothers for me to be comfortable shipping them romantically. While they aren't blood-related, they still see each other as family, so I'd rather not try ship the two.
I wish NRS could have at least considered making them a canon pairing or even just hints at romance instead. There really was so much compatibility between the two in MK9. That time around there was more leeway to choose if you wanted to pair them as a ship since it was established they were childhood friends. (I constantly analyze just how well-established their bond was the first time they appear in MK9s story!! I could go on and on...)
While I don't ship them romantically in the new era, I will still be happy to draw the two together in non-romantic but still closely bonded settings.
