Come to think of it, P2 would be an excellent choice for a DX. Sure, the PERS would be almost pointless (if they could do it, great; if not, it's okay), but the amount of high-quality accessories they could supply with the figure would be huge! A DX P2 could include newly-redone components of the old BD P2 and the regular, plus some of the accessories they missed:
Accurate rebreather
Seperate medical syringe
Fold-out metal saucer for his blue medical gunk
Switch-out stump arm using their new peg system
The actual severed hand that goes with that stump
Trophy-cleaning equipment (scalping tool, that vacuum-type thingie, skull-buffing tool)
Netgun you can actually put in the figure's hands
The famous spear tip
King Willy's head (eh, why not)
Either a rooftop perch or a section of the meat-packing factory with a hanging beef slab (as the fancy base)
