The Pro Micro and Leonardo have almost the same electronics. A difficulty is that Arduino boards tend to have a different pin numbering, making iit more difficult to find out which actual ATmega32U4 pin is where.
I found this chart in the Wiki that brings them together. (AVR pins in yellow)
That leaves the bootloader. I know people have flashed the Leonardo with avrdude - and there should be forum posts about it out there to google for
