Implementing custom texture filtering

Question

I would like to implement alternate texture filters (e.g. 2xSAI, Hq2x, etc). I am at a loss for where I would start with this or if it is even possible without lower level access to the rendering engine in Unity. Does anyone know how one might attempt to accomplish this?

here are most of the original scaling and interpolation shaders including 2xSAI, shouldnt be to hard to convert one of them into a fragment shader that you can apply to a material in unity.
