adafruit 8x8mini LED and 3cm OLED display Answered

Hello all,
I am building a Arduino WALL_E robot for my son. I am using 2 x 8x8 mini LED arrays using TWI and I would like to add on a small OLED (0.96inch) display. Both of these require pins  a5 and a4. The 8x8 led arrays using the adafruit_ledbackpack library and the oled using oled_12c Library. I dont know how I can get the OLED onto another set of pins.

can any one help?
