In this project, the two Pis won't be able to be grounded together,
Why not? You've got wires going from one Pi to the other, why not add a 0V /Ground wire as well? Connect pin 6 on one pi to pin 6 on the other Pi and you're done.

Otherwise could you show a diagram of your wiring and explain what the problem is?
