There is a "Primeval" figure that is in a suit, quite similar to the suit Donna Noble wore in the Doctor Who episode "Partners in Crime". I simply switched the head to a Donna Noble head, but the hair didn't quite fit the new body. I then replaced Donna's hair (easily removable) with that of another Primeval figure and painted it all a matching color. There was also a slight gap between the head and the new body, so I lengthened the neck a bit using epoxy. A simple red paint job to the under-shirt and VIOLA!
