CASA may want to do a functional assessment. Do you have a multi rating? If so, you could get a friendly FOI and DAME to organise an assessment flight.
CASA are quite flexible, as long as you can demonstrate the ability to control the aircraft, emergency egress, etc. I know of a bilateral amputee flying KingAirs for the military. He also holds a CASA Class 1, and a MECIR. There was a similar process to be followed with him.
AS FD said, most employers are only worried about whether you are appropriately qualified and experienced.
