How often do you pull your cranks?
If it's just for the annual service and you already have a crank puller, then I don't see the need.
Stick a ball bearing or two in the allen key hole if you are worried.
How do you get them out again?
With magic
Or nail polish remover, if you are worried about discolouration use boiling hot water.
