Ability use system head values to adjust features

The Marine head fits so close to my shape, except for the cheek structure and chin. I so much wish I could tailor that cheek and chin width somehow. It would be wonderful it you could add in capability to adjust for some of the unrigged values to custom tailor for uniqueness. I would not want to go mesh head if it lost my look.

Also, please add tasha2 for head skinning?
