Levo into dextromethamphetamine from seed crystal

[Astralketamine]

Just a question. Would dissolving a dextro crystral into liquid and then crystallizing it after or while adding drops of liquid levomethamphetamine increase dextro yield? Idea from this article. https://physicstoday.scitation.org/doi/abs/10.1063/1.1955467?journalCode=pto

Note that the experiment involved crystallizing one enantiomer of a racemic solution. There's no mechanism for chirality to swap in amphetamine so if you attempted to crystallize pure l-amph then there would be no d-amph present to form crystals.
