Getting snow piled up in block and partial layers is possible. CraftBook and some smaller plugins have shown this.

Picking up snowballs with bare hands is possible. And adding a small damage effect to snowball throwing too. Think plates. Snowball fights are much fun.

Also possible: Thickening snow layers during snowfall and partial, slow melting in daytime sun when not snowing. Will heavily affect cpu / mem though ... not really fitting for this mod I'm afraid.

I guess it may require some dedicated block coding to let mobs and players slowly sink in powder snow ... but you just don't sink in snow like you can in quagmire. A better alternative may be to add a slowness effect while walking on snow, with an effect strength dependent on layer thickness.
