Manufacturing Scadrien Identity Minds?

[Trusk'our]

I found these quotes in the Arcanum.

Quote

Krios (paraphrased)

If you have a form of manipulating your Identity and a form of healing, are you able to shapeshift or even evolve your body like growing wings?

Brandon Sanderson (paraphrased)

You'd have to do some real work on your Spiritweb to make that work. It'd take more work than you're implying, but the [singers] for instance are doing this. It'll take a little more work, it's not just blanking your Identity. Hemalurgy would make it very easy, but also very evil. But what you want to achieve is possible.

Questioner

What happens in cosmere terms with Parshendi? Like, they Connect to a spren. And then, by it do they change their Identity, or what?

Brandon Sanderson

Yes. Basically what's happening is, that symbiosis has a similar effect to Hemalurgy, but not so nasty. And it's being reflected there in the Physical Realm.

So it sounds that by changing your Identity you can make "minor" alterations to your physical form, and it will also make some alterations to your mental faculties, though your memories and your core personality will remain intact. This won't let you grow extra limbs, switch biological sex (probably; I'm not totally sure on that one), or change species, but I can still see uses for it's manipulation.

Perhaps you could, therefore, get a Singer to fill their Identity into an Unsealed Metalmind while wearing a specific form, which would allow a human to tap it and gain access to that form. Or perhaps Scadrial and other worlds could use this method for cosmetic purposes; hire attractive and healthy individuals to store their Identity, then use compounding to mass produce Unsealed Identity Minds for those who can afford it.
