On a side note, there is no such thing as cross-sensitivity because red, green, and blue are what CFA says they are. For a serious work, sRGB is a sub-optimal choice, because a lot of colour clipping happens when converting CFA RGB to sRGB (all the negative values from such a conversion are clipping). For better colour, try computing a colour matrix for your particular camera.
