I would LOVE a Lara set that have you spare parts to make her look from Legends/Anniversary/Underworld. Any other Lara Croft look would be amazing.
Skeleton Himiko, while nice, isn't a must have IMHO. Just give a pack in skull head and put it on regular Himiko, who is shelf warming (ish) anyways. Another Lara, a Scvanger and 2 more Oni, all with extra parts, would be the normal knees to cap off this perfect series. Too bad there wasn't something for the definitive edition.
