Warp Core Shape Variety

Currently the only Warp Core model is a torus measuring 5x2x5, a volume of 50. I am finding that this shape is limiting what overall shapes my smaller CV's can be. I think it would be great if more models for the Warp Core were added to allow for more variety in CV shape.

For example:
Shaft / Cylinder that is 2x2x12
Sphere / Dodecahedron / Icosahedron that is 4x4x4
Cuboid that is 4x4x3
