LCD, no way that I am aware of. There is also no straightforward means of using the X3 pro switch or front panel without some serious and creative splicing. I've created a schematic of the X2.6CE switch panel which would be helpful in figuring out how to make this work, but I haven't seen anyone dissect an X3 switch yet. They are completely different in design so it is probably more trouble than it is worth.
I happen to think the X2.6 switches are pretty sweet, it is big improvement from what I originally had with my X2.3 chip.
