I'd like to see the mess in a side story if he does plant a body.
The way I see it working is whatever is planted is grown in a similar condition. Plant a dead body get a clone of that dead body. Plant a live person and they're dead before the "plant" grows so you just get another dead body. How's he going to explain why there was only one town prostitute, but he has to bury 10 of the exact same prostitute in the same night?
Maybe even a joke crossover of Akina Shoji x Burke & Hare.
