I think it's possible, Rodney build a custom board for cubex (similar to 3d touch) and Jetguy and BikeJunky move their printer to a sailfish firmware with a Mightyboard Rev E.
Their is an other google group where you will find more information about this, the clone group :

Maybe Rodney will answer better than me to your question as he has this printer.
