Might as well put some lube in the hole on the side you drove it out from before you drive it back. Never seize would be good if available. d.d.

A friend of mine tried the breaker thing and had his pin so mushroomed afterwards it was like the pin was part of the casting
ending up torching that one out.... the tricky part is isolating the impacts so they do not swell the pin.... this is where you really need a second smaller pin pushing tight on the stuck pin before any impacting takes place!!!
If you are going to try to 'ping pong' the pin I would sand/grind the exposed end of the pin down a few thou. then lube it up also anti seize the bore on the other side. Since you mentioned replacing the pin anyways

If the pin is soft enough to drill drilling holes near the outside edge of pin should relieve some pressure on it,making it easier move

Personally I'd go for an exothermic torch and carve lengthwise right through the middle of the fecker. That's exactly what those torches were designed for.
It'd fall out then........!!

You don't want to make it too noticeable on a rental machine or it could cost you a bunch.
Why is a rental machine being worked on by a customer anyway?

Because the rental place is closed due to the virus.

If we are going to replace the pin, how about sawzall either side of the cylinder and take it out...I read earlier that the pin is free in the cylinder eye. Then, put a porta power in the center (they can be rented very inexpensively), and push. One side will move first. Once it is out, you have a clean shot for a drift with a holder and another person with the BFH (technical term). No mess from heating, and the cylinder is out so you can take care of having it fixed while you get the rest of the pin out. Just a thought, and shouldn't be a problem getting those tools to a remote place.
