Great question! The thing is we got to take into account of how the serum is made. It would surely be impossible to take a mindless titan's spinal fluid without the risk of being killed or destroying the particular titan. So to answer your question, if they were to be injected with a titan shifter's spinal fluid they would end up becoming a mindless titan. As titan serums can only affect Eldians it is unknown if ingesting it would have any possitive effect as Rod Reiss improperly ingested one by licking the floor:



Yet Eren is able to injest a fluid that contains hardening abilities.
