External editing tools like that are permitted. Unreal's terrain wasn't done in UnrealEd either!

Obviously we could make similar shapes in the editor and try to use the skin or other textures if necessary, but is that extra enhancement allowed or not, even if the final result uses BSP and the stock skin of that mesh?
I don't see why not. You could achieve the same by importing the meshes into a modeling program and then exporting as .t3d or .obj or whatever. It doesn't break compatibility and it's not a new ENGINE feature, just a fancy-shmancy extra tool built into the editor.
@Qtit He's talking about doing the reverse thing - converting old Unreal vertex meshes to BSP. No static meshes involved.
