Bejing Airport International Transfer

Hi,
we have booked our flight from bangkok over peking to munich with the airline air china. Now the departure time in peking has changed.
Our flights now are:
04 January Flight CA 960 BKK/PEK 19:15 - 00:55 /+1
05 January Flight CA 961 PEK/MUC 01:40 - 05:05
We hope you can help us with our decision. My wife and I are 34 years old and in good shape. Do you think we can get the flight to Munich in Peking if we hurry up. The transfertime would be correspondending to the plan of air china 45 minutes. May be we can manage this with the cabin crew, that the deboarding in peking will be faster for us. We think both flights arrive and depart from Terminal 3. If the baggage is not on board, this wouldnt be so bad. They could send on later to us.
So what do you think. Can we catch the flight to munich.
With best regards from munich
