Late model like an S*R monster or 696/1100 era? Either way it's possible but it's going to cost an un reasonible amount due to custom fabrication work. There's plenty of high mount options for your or any double sided swingarm monsters that are bolt ups.
As far as the flywheels most folks like the Nichols one. But being in Austrailia you might check with VeeTwo. They make nice ducati parts and you wont suffer international shipping fees and exchange rates
Its still cheaper to buy parts from the US and have them shipped here.
