Not possible. You need at least 2.5 hours in between flights subject to immigration flow and walk out from the terminal then turn around.

My last flight the luggage has been slow-ish to come out from the belt.

30 minutes from the jet bridge to the departure check-in facility is doable but depends on the visa-on-arrival facility (no queue at immigration but chaotic queues likely in VOA counter). Unless you do not need visa and do not have check-in luggage then you are still subject to check-in cut-off time.

There are cheap hotels in PNH, stay one night will not add too much cost. Cheers.
