Customizing second (small) screen

I understand that secondary screen is limited to the customization due to PCI compliance and security. Our use case is bit different and wanted to ask if there are any possibilities to get this going. I understand that Poynt was designed in a manner that second screen is always in front of customer. In our use case, we would want to turn the large screen to customer and small screen to receptionist. Obviously receptionist wouldn’t be needing any of those standard screens provided by poynt. The whole credit card charge flow would go through large screen while we wanted second screen to be used by receptionists to key in basic service amounts for different service professionals.

Do you think something like that would be possible?
