The desire to have a GUI which allows you to create new classes or styles for LaTeX could well be the basis for a completely separate (but complementary) project.

However, really, two projects are needed; the first is as you described and could be used by non-lyx latex users though I don't know how many of them would. The second would be a GUI for constructing a lyx class.layout file corresponding to the latex class or style file.
These are separate (but complementary) projects, at least in principle, so the lyx team could in principle implement the latter (once their todo list is sufficiently short of course).
In the meantime the class.layout files are not so difficult to do manually.
