This is what I've done the last couple of weeks. I've gotten as far as this:

Probably not as high as one should jump when practicing this move* but I think moving up a pallet every other month or so will bring some results.

Right now I'm at a point where I still have to visualize the move before doing it so that the technique still isn't quite right. For example, I should lean more over the handle bars. I think it's like everything else in trials. Practice x1000. 

Again, sidehops but of a different kind. I like it much more than the "real" sidehop.
