Hi,
The following link takes you to the HRCR technical site for a cat 2 mini. This states you can use a weber carb, so that would indicate you must be able to add an air box. It also gives some other interesting options.
Another question though, can you use 4 pot brakes.

Like you say it is all a minefield and the changing regs do not help the clubman and his costs.
The question the scutineer will always ask....can you prove that the modification (in this case 4 pot brakes) were used during the period? So were they even invented? Did the works teams use them on the rally cars (they'd be the first to use them if anyone did)?
If it's no to those and you cannot provide documented evidence (articles in magazines etc) then they will politely tell you that you can't use that and ain't running in the event.
A friend of mine entered the Tour of Cheshire in his Morris Minor fitted with disc brakes. He failed scutineering as Minor's apparently never had discs.
On a different note.....
The only people who can actually stop you competing in an event are the Noise tester and the Clerk of the Course. The scrutineer can fail the car, but its the CoC who says YAY or NAY. Thats what i was told anyway.
