Any reason not to slope the shower subfloor?

I'm about to embark on a DIY full gut reno of a bathroom, including subfloor replacement. I'd like to use a linear drain (Kerdi-Line) in my 3'x6' shower, and was initially considering purchasing a preformed foam slope board. However, I can't see why I wouldn't just notch my joists and slope the subfloor itself. It would be easy to do, and would save me the expense of a pre-formed slope. I would then use Kerdi over Durock (or the like) on the walls and Ditra-Heat over Advantech on the floor, Kerdi-banding all the seams.

Does anyone envision a problem with that?
