I don't think a titan ingesting Zeke's spinal fluid while Zeke was still alive would do anything in regards to passing on his beast titan. The currect holder has to die before anyone else can receive the titan.

What we don't know is, maybe it would allow Zeke to control the other titan with his powers, maybe not.
