Not sure how far you are willing to go on this, but this is how I would do it:
Compile all the colour correction shaders into a simple LUT texture and then manipulate just the Reds in Photoshop to change their hue. You can't do this in SweetFX as you can only choose between the RGB CHANNELS, not isolate Red by itself. If you mess with it in SweetFX you are going to be changing the whole image. So if you want the preset exactly how it is now, and only change the Reds, this is the way I would do it. You also get to use just the LUT and disable all of the shaders that you used to generate the LUT, resulting in a performance boost. Looking at his screenshots, you would need to change the greens as well as they are quite cold.
So that's an example using just a LUT. If you want to go that route just reply back if you need help doing it. The LUT used in those screenshots was from my preset if you want to just use that instead.
