Ballistics impacts & other violent VFX/Particles

This looks great.
Some questions:

  1. Are the effects easily* scalable in size, the volume they take up?
  2. Is it modular? If I for example only want to use the bullet penetration system and oil fx, can these parts be easily migrated from the template?* I would like to prevent having a tangled mess of folders in the content browser.

*easily in this case, someone with beginner experience in the material editor and blueprints.
