You could try, but I think it would be very hard. Even if it looked approximately right, there would still be a lot of tweaking to do; I had to do an awful lot on my Dwarf Worker, and he was the PDM, just distorted. You also might well have to re-do some of the more tiresome prop bits too, such as the soil in the Road animation.
It would probably be simpler to use the PDF, if you want something Aiko-like, perhaps with some morphs to increase the resemblance. Then you can simply parent it to the PDM in the file and make the PDM invisible. You might still need to tweak the model slightly (I found that she needed her forearms lengthening to match where the props are).
But give it a go anyway - you never know!
