I was thinking about using a Rex head (with a hair repaint) to get a photo real Jango, until I got both figures together and found that Rex's head is SIGNIFICANTLY smaller than Jangos. Odd that, given that they're the same scale.
Or that is should all be computer sculpted now, instead of various artists? Leading to such issues of varying head sizes. Honestly it should essentially be Jango, then just modify the hair sculpt accordingly.
