This sounds much like a method I use (I think it was posted here last
year but I don't remember who - sorry I can't give proper credit):

1) Add Hue/Sat layer but don't change anything yet.
2) Add Chan/Mix layer and do the usual things with it.
3) Back to Hue/Sat layer: move the Hue slider to get the effect you
want (can give red or yellow filter look, etc).
4) Flatten
5) Convert to grayscale mode
