it may be possible with different prompting, sure, but my best methods have proven to yield that old to young is adhered to by the sampler on steps 1,2, but by 3 and finally 4, she's a child the whole time, because the denoising tries to match the girl's face to the end goal. i'm literally watching it happen realtime in the sampler preview.

so far i'm only able to get the switch from old to young if the transition takes no time. i'll keep experimenting.
