Maybe, but not easy.
A few things to think about:
I've found that oaks tend to prefer deep containers that allow more root mass.
Willow oak leaves reduce, but I doubt you're going to get TINY leaves in mame scale.
Oaks are notable for their stout, substantial trunks. An oak bonsai without such a trunk really doesn't have a lot of interest. To get a substantial trunk for a mame sized oak, you should probably start out with a more developed trunk and work it down to mame size. It's doable, I think, but you're going to have to find the right trunk to start out with and take a few years working the root mass down.
