LED strip.

There is no such generic profile.

You can create a profile like this, but you would scarifice individual control of the colors. The sum of the two colors (before applying Intens) would always be 100%. There would be w100/c0, or w50/c/50, or w0/c100, but you couldn't have w100/c50.

I understand the mix would not allow individuals control but how do I go about creating a profile like this? 

I realize I may have misread your question. I can offer a profile that does control cool and warm through one single parameter. However I don't see a way to do the color control through one single DMX address if the controller of your LED strip doesn't natively support it.

The cool white fixture profile is a copy of the warm, the only change is that the User Min and User Max values are swapped.

I chose 3000 and 7000 arbitrarily as Kelvin amounts representing the warm and cool mixed colors.

Are we over thinking this? Could it be patched as 2 seperate dimmers and just mixed to taste? If the LED strip has 3 contacts (Common WW CW) this would be easy to achieve. and of course you will need a LED controller of some sort. 

insted of using 3 Parts i would use/create a fixture with:
1 virtual Int
2 Color-parameters (warm and cold)
