Given it's just one them the UK superbrand again, I am not sure there's an urge to change somethinfg that remains incredibly effective
The example given is more an evolution of current branding, keeping all current elements of the brand for marketing and corporate use intact. The suggestion was, if the livery was to be used, the red on the tail should be drastically reduced to a taper copying the style of the "ribbon" on front fuselage, which would allow space on the tip of the tail for the Crest, as it appears on the "Landor" livery (Inset on original post), which had itself been reversed/inverted in colour from predominently red tail fin on previous livery to accomodate Crest:
Evolution ?
