Don't know about Bahamas regs but,
Most aviation authorities require a Type rating to fly a Jet. The FAA doesn't as SIC.
Doing a type ride entails Commercial/instrument license at the very least.
Of course, as mentioned above, insurance would be unavailable. Unless maybe the guy being insured was also the owner of the insurance company.
Under FAA reg's you would need a high altitude checkout to fly a pressurized high performance airplane, and in most airspace in the world that would entail going high enough to require a IR rating.
Ultimately speaking it might be " marginally posible", but definitely not practical or safe and very absurd
