Don't know much about it but from a reuse point of view would that require a C of A ? and would that not require a design authority and an OEM spare parts supply for the airframe and the Tyne's. Cannot see Shorts and Rolls Royce being about and up for that.
In that case I can only assume it'd have to go on a permit to fly, like the Vulcan, which puts all sorts of restrictions on it, like limiting it to the country where the permit is issued and prohibiting commercial use.
Seem to recall all these arguments being rehearsed when the bearded pullover wanted to bring Concorde back.
