Question since this is neostandard shipset: what is the nameing convention if I want to do a variant as say heavy destroyer or scout?

The convention only applies to the filenames.

So if you are modding, you can use any of the names specified.
If you are making a Shipset, create as many as you like, and then my Neoshipsetbuilder can fill in the gaps.
