Ah, I'm so happy to meet another Qi Rong fan! Oh god yes, there is so much competition in TGCF. I have a really hard time picking a favorite. I am very weak to Hua Cheng, but Qi Rong is definitely in the running, because he always makes me laugh when he shows up, and I love his chaotic energy.

I'm mostly canon-blind to TW (I've picked up a couple bits of info here and there), but Kalim seems great! Based on your description of him, I can see their CR being hilarious, no matter how it goes.
