Removing/modifying existing parts of a model in Blender.

Hey, so, I was wondering if someone could explain to me whether it is possible to actually edit the model structure of a model.

I’m used to kitbashing, if I can get this to work I might be able to create a Mandalorian model without the antenna, modify the First Order stormtrooper to have ridges akin to the Sith Trooper, and make Sith Eternal officers.

It is: just select the mesh, enter Edit Mode and play around with the parts you want to modify. Just a note though: while removing part of the geometry of a mesh (like the antenna you mentioned) generally has no dire consequences, if you want to add to an existing mesh you'll also have to UV unwrap the added geometry and make sure it doesn't interfere with the rest of the UV map.
