If you are going to use peat moss, then it's not advisable to use too much. A general rule of thumb is to use only enough to cover the bottom of the tank so that you can still see some of the glass bottom showing through. Otherwise, it makes determination of CO2 concentration virtually impossible, due to the humic acids released by the peat ... at least for a while until all the peat is spent.
Regular Turface (i.e. Profile's Aquatic Plant Soil) looks like clay. There is also Turface Gray, which I assume is gray? Nonetheless, from what I have read, it is quite difficult to source the Turface Gray. If you are pleased with the original color of Flourite (i.e. not the Flourite Red), then regular Turface shouldn't bother you.
I've used regular Turface for a better part of a year and although it is relatively light, I never found it to be a problem. Try it alone first and if you find it to be too light then by all means add something else to it; but please find something that match the color of your substrate. Otherwise, it would look quite aesthetically unpleasing IMHO.
