Show two currencies in Backend

Hi,
I am looking for solution to have two currencies on backend. I mean to show default currency details as well as changed one.

I have premium version of plugin. My main currency is USD and in this currency I would like to send invoices to clients but I need more information in USD.
When somebody buy product in different currency e.g. AED Woocommerce > Orders show details in AED, also I receive email – new order in AED.

I wonder if can I show still main currency in brackets as on attachments. Both places (orders, email) would be perfect, but important place for me is email.

I have to replace: woocommerce/templates/email/admin-new-order.php
But I dunno get those information in php.

do_action( ‘woocommerce_email_order_details’, $order, $sent_to_admin, $plain_text, $email );
I have to edit $order somehow.

I hope I was clear enough.
PS. Note this is production page. Please be careful 🙂
