In principle, I rather like the idea. It harkens back to the 1920s and 1930s when luxury cars were given special bodies -- usually one-off custom designs.
Rolls-Royce's public relations web presentation includes the following:
"Still in its concept phase, Project Nightingale’s aesthetic is grounded in the belief that the most exquisite design emerges from precision, where function and form are inseparable.
Project Nightingale also draws inspiration from Rolls-Royce's red-badged 'EX' experimental prototypes of the 1920s — particularly 16EX and 17EX — some of the rarest and most desirable motor cars in Rolls-Royce’s history.
These foundations informed Project Nightingale's three core principles."
"Coachbuild Collection unites a true coachbuilt motor car and an extraordinary multi-year programme of experiences.
The clients invited to join this remarkable programme have a special affinity with the brand. As collectors of one-of-a-kind opportunities, they will be granted rare access to the innermost design studios within Rolls-Royce and gather for events in the world’s most desirable destinations."
"As the most exclusive division of Bespoke, Coachbuild is the automotive equivalent of haute couture. The invitation-only service offers individuals of extraordinary achievement, culture, and vision to craft an entirely original motor car — and stake claim in the marque’s legendary history."
That said, let's take a look at the associated concept car, along with my commentary. I need to note that it's electricity-powered (or intended to be so, if that car isn't functional). I think that is not a good idea, given the problems inherent with that technology. But seriously rich buyers might not mind, because they would have other, more practical cars available.

The grille is similar to Rolls grilles of the past decade or so. The vertical lights on the fender fronts are in the spirit of current Cadillac and Kia designs -- not unique.
The profile is in the same spirit as recent Roll sedans. Note the "suicide" door hinging.
For some reason (Teslas?), electric car styling by many carmakers tends to be simpler than styling of conventionally-powered equivalents. Same story here.
Concept cars often lack bumpers because those could interfere with the intended visual concepts presented. This car does have bumpers, but they seem too puny for everyday protection. A front bumper that's a bit more forward of the grille might work.
But the tapered rear bodywork seems at some risk, given the bumper seen here.
Cockpit view. Instrumentation is hard to detect. Maybe it's all in an electronic screen that's not activated in this image.
