Do not remove the steel pads, they control the expansion of the piston.

You could weigh the connecting rods and pair the heaviest piston with the lightest rod.
That would not be the best method. Rod balancing is done in two steps. The large end is considered as an assembly that rotates around the wrist pin then the small end is considered as an assembly that rotates around the crank pin. Simply picking a heavy rod and mating it to a light piston discounts the rod balancing procedure and doesn't resolve the piston imbalance.

A careful guy with an end mill in a drill press might be able to remove some material from the crown. Additional careful work around the pin boss with carbide burr then a sander in a die grinder will finish the job. Since these are not diesel pistons and they are presumably not subject to positive intake pressure they're likely to be plenty strong enough.
