CC Page Turn blur?

So, I'm using the good old page turn effect but want it to look a little more realistic.

As we all know, adding a little motion blur to moving objects always helps this.

There's no such option in the effect panel. I was thinking about creating an adjustment layer, applying a directional blur to it, and then key framing a mask so that it followed the page's edge.

It looks okay.

Anyone else think of a way to do this?

Thanks.
