Emulate MovieTexture With Dynamically Loaded Images

Say I have a short video and want to play the video in a scene in Unity, but I can't use the MovieTexture feature because I don't have a pro license (yet and I'm still trying to get a free 30-day trial). Is it technically possible and feasible to dynamically load images (in a flip book fashion) in order to emulate a video being played in a scene?
