I have done it a couple of times without a problem. It is a little tedious but if you follow the service manual it can be done. I placed each part in a small plastic bag as it came out and labeled it as to location, right/left etc. Digital photos in various stages of disassembly would also be helpful although I didn't do that. Most of the action parts have to come out to get at the block that holds the firing pins.
Who makes or rebuilds the plunger assemblies. I know Laib probably sells them, but does he make them. I am afraid that some day he will run out or quit making them. I had a friend who rebuilt them, but he no long does that.
