The OP posted the same question to Travelbuzz - worded slightly differently, and stating that they were planning to check baggage, and to have to collect and re-check it (which would indicate separate bookings). I expect the two threads will be merged in due course.

I replied to the Travelbuzz version of the question suggesting that the connection is too tight. Without checked baggage, or if baggage is checked through, it's entirely do-able, but if they have to collect and re-check I'd say "no way".
