shapkeys 2.6 BGE

hi everybody . i would need to know if its possible to keep and mix the animations of shapekeys in the 2.6 bge (play them simultaneously like move one eyebrow and on top of it the other) …like in the attached 2.49 blenderfile.
what i would need to know is how to convert this file to have it work in blender 2.6
cheers,e
