Emag the cloning tube directly to turn it into a shambling meat factory.
Aggressive grab a body, alive or not, straight into the tube to begin processing it into a shambling meat goop.
If the body didn't have a client in it, then the shambling meat monster just uses killer tomato ai and considers its creator a friendly.
If the body had a client in it, then they get given objectives to aid their creator, also MEAT.
The cloning.dmi already has sprites for it:
Would probably need sprites for the mob though.
