Is it possible or even constructive to make a game without any graphics (but is intended to become graphical)

I'm not good with graphics at all, so I'd like to write the skeleton for the game then have a graphics programmer/artist fill in the rest. I could write up all the major classes, and their interactions, and all the major functions/parts of the game.

If so, what should I do to make it easier to integrate graphics into the game later on (every drawn object should have a Draw, Rotate, Collide, etc method) ?
