Md2 doesn't entirely rule out sswift's shadow system. You could cast the shadow from a static dummy head instead of the animating visible head; the dummy won't have facial animation obviously but movement that subtle shouldn't matter for shadows.
Md2 does have a number of other issues too (eg. poor DX lighting) but is the easiest way to get morph animation into Blitz.
