I'd take another Anakin if it were sporting a soft-goods cloak and 14-16 points of articulation... Preferably with heavy use of the ball/socket joint.
Could be a cool figure, but it's hard to say if Lucasfilm would be approving of a corpse figure of Shmi... So far the closest we've gotten is the non-descript torso with Amanaman...
I'd certainly not turn my nose to a new Anakin that had a bit more articulation and bit less pre-posed sculpt (Secret Ceremony Anakin's legs are bowed for some odd reason... That figure should've been much more neutral).
