Use FT232 to porgram Arudino Due , SAM3X8E unsed pin

Other Hardware 3rd Party Boards

Hi all, I am trying to build my own Arduino Due and I am wondering

  1. if I can use the FT232 to program the Atmel SAM3X8E instead of using the ATMEGA16U2 ?
  2. Does the Arduino IDE support using FT232 to program the Atmel SAM3X8E ?
  3. There are some unused pin in the ATMEGA16U2 PC10,PC11, can I use the PORTC = ... command to control the PIN in the IDE?

thanks for you all
