Question! An extra head project... (Soom Trachy)

[Beth-chan]

I have a project that I'm starting up because I have an extra head that need a body. The vision is to make a young girl to be Raziel's twin sister. However the body & additional features(like horns) may pose many problems.

The doll is Soom Trachy, the head is the open-mouth face.

So I need to either get a body & dye it red or make a body out of red material.

So I have a few questions:

One: What sell-alone bodies fit these heads?
Two: Is an at home dying method possible? (any tuts would help)
Three: Would making a body from scratch produce a better color match?
Four: Can a yoSD body be made out of sculpty? ( like with stand the pressures of elastic without breaking.)
Five: Can sculpty be used for the small parts? (horns, tail, etc.)

I know I should have bought the extra body at the purchase time however I didn't have the money so I'm welcoming this long & challenging project.

Wish me luck!
