Skill cost question

Is such a thing ever referenced in an Official GURPS product, or is this strictly a fan-made way of making FMA-style Human Transmutation prohibitively expensive?

Note that Techniques can easily default to a skill, even a Very Hard skill, at -20 (or worse).

That makes it impossible without a lot of training, which might be the desired effect.

Requiring an expensive prerequisite, such as an Unusual Background, for example, can then add to the starting cost as much as the GM wants.
