Odee if only as a windage fit then I think the strength addition is just in the new studs, now if the bridging between the 3 caps is intergral to strengthening the design I think the whole assembly has to be torqued up to be of benefit.
Alarm bells went off in my head also with the paint and what appears to be carbon steel, now if this were made of a quality unpainted stainless looks like it might have some merit, But I think probably the real benefit is in the better studs.
My initial impression/opinion anyway based on what I see in the post nothing other than that for my opinion.
