Adding a check signature to SQR Reports PAY003

We use version 9.2 and are currently on PeopleTools 8.56. We currently use customized versions of the SQR PAY003 reports to print out payroll checks. We have font boxes and signature cards attached to the printers for MICR and signature printing.

We are looking at adding more printers and want to move away from this approach and add the signature and MICR line to the SQR reports so we can stop using the physical signature cards. Has anyone had any experience with this approach and have some guidance? I do see this option would work with the Bi-Publisher option, but we would like to explore modifying the SQRs first if that would work. Thank you.
