Is there a way to configure my Paypal Pro Registration process to accept Bill Me as payment type next to PayPal button
Bill me as Paypal Pro Registration payment mode
No way - any payment, that don’t go trough s2M can not be seen by s2M, thus it can not react to them to set need level and/or ccaps to the user. Can be done with a custom payment gateway.
Well, technically speaking, it would be possible if you wrote your own payment handler…
