someone wanna get ballsy and trim the valence rather than remove?
This is really the only way to do it for it to look right. People used to do this on the NNBS Hybrids, and the K2XX front clip is almost identical in design to them. They'd cut out from 1/2 to 2/3 of the valance. I don't know if the K2XX valance is texture plastic like in the Hybrids, but I had mine sanded down and color matched, and it looked great.
The Hybrid valances are surprisingly cheap (like $120), and it might be the same with the K2XX ones, so it might be worth just buying one and experiment with it.
But yeah there will be clips and other bits showing without it, so the right way is to trim it and imo sand it and paint it.
