Given the plan to keep the weight down on the finished project, picked up a new rear bonnet from a Mini supplier I located on the web. He carries a number of parts in fiberglass and carbon fiber.

Fantastic quality, extremely well made, and super light !

To fasten it down, elected to go with a super cool flush quick release fastener rather than using the more traditional Mini handle or Dzus fasteners.
