There is a "built-in" Page Curl distortion filter. Trying to build the same kind of effect as the MotionVFX effect can be done... but it is not an easy task. The filter will curl a layer: what you see on one side, you'll see in reverse on the other (unless you opt for an opaque background.)
In order to get a back-to-back two-different-pages effect is going to take some work. Just layering the image in a group and applying the Page Curl to the group will not result in the desired effect. Page Curl is a 2D effect but rendered to give a 3D effect (you can tell by rotating the object of the page curl in 3D space and watching the animation -- it's "flat".) That doesn't mean you can do some of the page turns in 3D space, but you'll need to limit the Page Curl effect to a smaller percentage and work out a way to disguise the "flip over" of the effect in mid rotation.
For a "regular" 2 sided page turn, you can try:
Add the Page Curl to each "page" image (you might consider linking properties of every other filter in a page set.) [Also, all "pages" should be the same size.]
Set the Back Color parameter in the top page view to (100%) Green or Blue and apply a Keyer (no other parameter settings should be necessary for the keyer.)
Set the Highlight Color to Black (any other color will likely interfere with the keyer.)
You might also want to make a "left set" and "right set" and have "opposite" animations to give some variation to the effect.
That might get you started.
