Great points Markus, I answer below

Freeze plug is designed to hold back heated engine coolant at a high pressure, should be more than up to this task.

The place where it will be driven into IMS tube is at the very most supported point in the entire IMS assembly. Deep inside all the reinforcement around the sprocket. It can push against that casting, same as the bearing just with a tube in between.

It is a very lightweight and symmetrical part, I am not worried of this.

Freeze plugs are removeable HOWEVER I would not use a freeze plug with anything other than an uprated center bolt. If the center bolt fails you will have to drive the freeze plug deep into the shaft to remove the broken bolt OR come up with a way to pull via the stub of the original broken bolt.
With an uprated center bolt, I cannot see it snapping when you pull, so not really a concern.
Rather than calculating pressures, I am trying to source a damaged Intermediate shaft to plug, and then put an air pressure gauge onto, then just stick it in an oven at 300f and see what we get.
