its a real simple job, as long as the holes are maked out correctly, equally spaced and centered on the roto, the only other potential problem would be that the holes were fdrilled at and agle, thats kinda hard to do when the roto is secured to the mounting surface of a mill.
You're probably better off getting rims custom drilled, some shops might be willing to special order you some wheels from the factory with the proper offset and lug holes/spacing.
It's un-safe if you're considering modifying the stock components. Otherwise, a five bolt set-up is stronger than a four bolt.
With regard to the Honda, Acura Type-R (becasue they're easier to get) components are used; larger axles and CV joints, bearings, brakes, calipers and rotors - oh and new wheels. About $5,000 dollars...
The plus side, the NSX calipers will fit Type-R hubs...add another, I don't know, $2,000.00
All said, this is a bolt-on modification with readily available parts that costs $5,000-$7,000 dollars. Dunno what a properly designed and built one-off would be for a Mini - lots more.

Thinking back on this one for you, if you retain the current bolt circle and simply convert to 5 lug that's not going to be as much of a problem. You'll re use one of the current holes and have two others very close to the old ones. If, on the other hand, you want to got to a larger BC then you've got a mess on your hands.
