The origanal plan at JQ was to take the -8s setup the network, take some -9s and give the -8s back to QF as transcontinental machines. Hence why they were setup without crew rest etc.
The tanks are the same size, 101 tonnes of fuel.
The engines are 70k (although originally 64k)
335 seats
30 tonnes less MTOW so range would be about the same. (Average 4.5 t/hour burn)
As for the second part, that sounds like it could have been possible, the -8 would be a good City Flyer machine.
