I understand that you're aware that you can only have 1 payment method in 1 form. You can actually have 2 payment methods in 1 form.
The solution is to create another form that has a payment method on it. After that, embed that form in the main form that has a payment method as well using the Iframe embed widget.
Hope that helps. Thank you.
