The Creature Morphs for M4 and V4 come with a 3 fingered morph and facial morphs to get close to the look on http://images.epilogue.net/users/abi/the-Gargoyle.jpg , tho you'd have to work it.  I've been considering trying to make something like this as well.  A few resources I've purchased that I feel will help:

V4 Morphs++ (needed for creature morphs)
V4 Creature Morphs (also includes legs similar to your pic)
'Lizardwoman' for V4

The last one I got simply for the tail that is included, which is a awesome tail to work with.  scale it up and it'd fit that just fine.
The Morphs++ comes with a 'no fingernail' morph and the Creature Morphs comes with not only a 3 fingered morph, but the double knee legs as well.  I imagine some scaling would be neccessary to get the legs to bulk up to give us large claws on the feet.  My plans for the hands would be to apply the 'no fingernail' and 3 finger morphs and then do a pinch/pull/bend job on the fingertips with magnets (while I'm not up on creation of morphs, my results with magnets so far surprises me >.> ).  If magnets aren't your thing, could always use the claw morphs instead of the no fingernail morphs that come with creature morphs, but you'd get smaller claw tips.

Couple that stuff with the wings previously mentioned, maybe you'd get good results?
