Thanks Howard and Cindy!
Re the "as shot" color, I give all the credit to the camera and the conversion --- all I did was add a touch of saturation on conversion.
On the false color, I use the same color file, also with a touch of saturation bump (8 points in C1), then swap the R and B channels in CS. Here I've created a CS action that lays down a cleaning layer, a Channel Mixer adjustment layer for the channel swap, a Hue/Sat adjustment layer and a Curves adjustment layer. I then simply run that action, tweak the hue slider to get the blues where I want them, then tweak curves for contrast, then go back and adjust final saturation to taste. That's it, and about as easy as it gets
For a comparative, here is the exact same files as above, only the trailer processed as shot color and the girl processed for false color. Understand I do not prefer these options, just using them as decent examples to show which colors are affected and how. Note that a similar curve adds a bit of brightness to the false color version, and I have not sorted out the reason why yet:
