We might be more open to adding additional title systems, in addition to the simple, classic, size, complex, republican, democratic choices? That is, if someone had a proposal for a new system choice to be added, we could see about implementing it, but as far as complete custom choice, that seems unlikely.
In other matters, I have long thought that 'Royal's should be renamed to 'Prince's or 'Royal Prince's, as a better title text.
