I don't think that this would be in our/Mazda's long term interests. As mentioned above, expensive (for either, or perhaps both, driver/entrant and organiser - presumably Mazda), and not doing much (anything?) for motorsport, let alone grassroots motorsport. Maybe get some TV time, perhaps raise awareness of the ND, but ultimately going nowhere.
It could be run in conjunction with MX5 Cup and/or MSC, either using NDs (only ND drivers eligible), or on a contingency/prizemoney for
any MX5 driver. That would be my preferred option. Would have to work hard to get TV/other publicity though, but the impact on motorsport would be much greater, and potentially continue longer.
My 2c.
