Change a blueprint class' skeletal mesh at runtime?

I’ve got different ammo clips in my game with a different material for each one. My clips are spawned onto my gun. I have a clip blue print class. It’s very easy to change the material of an instance of a clip by using the ‘set material’ node on a clip instance’s static mesh.

I’m wondering if I can change the material of the magazine blue print class itself, so that all future spawned magazines have a diferent material applied?
