The pin doesn't fall out that easily but you do have to be a little careful.
Not saying this wouldn't work, though. Maybe you can machine a matching block that slips into the pocket with the relief / hardstop set for the right distance to allow this? That way you have a tool that can do both partial and full removal.

Good idea with the insertable hard stop. However, after the pin was pressed part way out, I'm not sure how you would get the chain turned around in the tool so it could be put back together, because the pin would be sticking out...

As it is a press fit, even under perfect alignment, it is having to generate some force before it slips back into the hole. That force can force things out of alignment if everything is not perfectly restrained. Perfect restraint can lead to some tolerance stack-up issues in an actual part/tool. It is my opinion that leaving the pin in the outer link is the simpler solution, but I'm also interested to see you try it your way and validate/invalidate our observations.

Good insight. You are probably right that pressing the pin part way out is the simpler solution. I'm also curious to see how the tool will work.

That is the idea. The threads chosen also have a minor diameter that is almost exactly the diameter of the chain pins being pressed, so there should be nowhere for the pin to go except into the chain links.
