You wrote: "History aside, doublet makers have always seemed to respect these conventions so it jumps out when one tailor does not." What do you base this statement on? Tailors do what their clients' request.
My "eye" in matters of Highland Dress has been formed by 1) owning a large number of books on Highland Dress and spending quite a bit of time studying the old portraits reproduced within 2) looking at many old portraits in museums and historic places in Scotland 3) collecting a large number of vintage photos of men in Highland Dress 4) studying the dress of the kilted Highland regiments and 5) examining very closely the dress in The Highlanders of Scotland.

This is in no way any sort of definitive or exhaustive list of sources, but it is a large enough "sampling" to get a good feel for what is traditional and what is not.

I cannot recall seeing a doublet made with tashes of a different colour from the body in any old portrait. My memory isn't perfect. But if such a thing occurs in an old portrait somewhere I probably would have seen it.

We sometimes have to keep in mind that Highland Dress as it has come down to us was perpetuated in the military. Military doublets respect the origins of the collar and cuffs being originally turned back and showing a contrasting lining colour. The tashes did not originate in this way, but were always an extension of the body. It's easy to see how someone not familiar with such things might, by false analogy, think of the cuffs, collar, and tashes all as added bits simply stuck onto the body of the doublet, and all equally subject to being done in contrasting colours.

Your statement "tailors do what their clients request" explains it all. A tailor may be highly respected and very expensive, but if a client requests him to make something that's at odds with tradtion, the product will be at odds with tradition. The product doesn't gain the patina of tradition just because it's been produced.
