Pretty good ‘conclusion’ to the ‘into’. 

Idea pretty much have been given.

Only two that I could add: someone is shrunk and then also told that they are extremely malleable but durable, that way they can be used without injury as an insole. The other is seeing the true limits of this therapy, even more so then telling specific sizes, (considering it can somehow change Hair) see if they can change it to more unnatural colour (someone who dons’t want to use dye and want it to grow that way), have particular patterns on the skin. Then how far limbs can be modified and if new in could be grown, cause some people would absolutely like to have cat ears or tails, and the other related animal traits. Extreme, but needs testing. 

Thought on further thought, and lightly less extreme, can senses be enhanced and his far. Cause human hear is already so food that only a few weeks and someone could actually hear all air moving in a room. So enhancement to eyesight to get more wavelengths might also be usfull. Possibly even to Clara.
