With Bank Deposit, the details will be included in the email sent to the customer,
You could possibly add the info to the

includes\languages\english\modules\payment\dirbankusa.php

I think around line 32

define('MODULE_PAYMENT_DIRBANKUSA_TEXT_TITLE', 'Direct Bank Deposit - USA');

try changing it to
define('MODULE_PAYMENT_DIRBANKUSA_TEXT_TITLE', 'Direct Bank Deposit - USA<br/> Acc No: 1234567890<br/> Bank: Acme Banking<br/>Branch: Waikikamookau');

And see if that gets the info onto the right page

And yes i realise i am not pulling the variables from the database, but its school holidays here and I have loud 3 and 4 foot terroroists charging around the house
