Currently, i'm making a one page checkout that requires this feature, the feature you're describing can be archieved by editing the payment modules views with the checkbox, and creating a button for your prestashop.
Please have in mind that this checkboxes will only work with this two modules, since i will be editing only those 2, if you add a new payment module in the future, it will use the default view it has.
I will give you assistance related to this, so if you add a new payment module later and require a checkbox option, i will gladly edit it.
