If I could relocate the button as in input to A5 or A7, then I could use Pin 11 to drive the LED. Any thoughts?
Is your button wired up using a pull-up or pull-down resistor?

Additionally, Are the SDA and SCL pins on the Mini Pro wired differently that the A4 and A5 pins?
I2C pins are still A4 and A5.
