You wouldn't be able to count the hours under the FAA system either. You can only log SIC time in a helicopter typed for multi-crew ops, you can log PIC when you're the pilot flying, or as an instructor. Safety pilot is nothing. So there's is no difference between the two systems.
By the way even if you would be flying straight and level in a type and log PIC, but you didn't receive training on the type employers and insurance companies wouldn't accept this. People seem to forget that PIC means pilot in command, the guy who solves the problem when it goes wrong, now you wouldn't be able to handle an emergency, when you don't have training on type would you?
