Looking for a skull!

[pezilla]

Hi all been reading on these forums for a while but never posted but i need some help.

I've just started my long term project of turning the large Forge world space marine from its everyday normal pose into a Black Templar's chaplain.
While i have an idea of what i am wanting to do with it i am having trouble finding a skull to the right scale and enough detail to replace the marine helmet and give it a skull helmet as sen on some of the GW chaplain models.

looking for some thing like this http://www.games-workshop.com/gws/ca...Id=prod1050243
If any body can help it would be much appreciated.

It's 16" so it may be a little big (not sure), but considering that it is replacing a helmet, larger may be what is needed.
Also have you considered sculpting (or having someone else) one of your own?
