Yes it should be and you then have a whole bunch of extra lines to play with.
A small bit of programming should allow a user customizable interface that allowed individual pins to be 'switched' and as long as they were buffered with a bunch of transistors on a bit of breadboard you could build a really nice bit of kit. It could control the LCD touchscreen, remote amplifier, neons, spinning disco ball (lol) etc and you could also use a scripting language to control all of the functions with timers or event triggers.
A bit of C+ programming should do it.
