I need to add a New Payment Method for US Postal Money Orders.

I need to add a New Payment Method for US Postal Money Orders.
It can be the same as the 'Pay in Store'(which I am already using).
I've used the Nop.Payment.Check already, now I need a payment method for US Postal Money Orders.
Is there a way to duplicate Nop.Payment.Check?

Thank you for you help.
Mike
