Swapping DBZ Figuarts heads
 

Hey everybody, new here and starting to get into customizing the DBZ Figuarts line slightly. First "roadblock" has been head swapping between certain figures. The original releases can swap out no problem as far as I've seen, but these new ones present a problem. 2.0 Vegeta can't swap with anybody, Saiyan Armour Trunks has his own head peg size, etc. Does anybody have a guide as to which heads can be swapped with each other and which ones are currently stand alone? At the moment I want to get a black haired Vegeta head on the 2.0 armour and I would rather just buy a Saiyan Saga Vegeta if the head peg is similar (I've repainted previous Vegeta heads and this would be easier obviously) so if anybody else has head swapped them it'd be very helpful if you could let me know! Thank you in advance.
