You can. bigger lines and stronger pumps have nothing to do with anything.
Vapour pressure aside, most of what you say is nonsense.
Aviation petrol is controlled for various reasons.
Octane: to prevent detonation. Standard service station petrol around the world uses different tests for octane rating, aviation petrol is the same.
Volatility: Petrol on the ground deals with fairly constant temperatures compared with aviation, so depending on where you live will depend on the blend. Aviation fuel on the other hand, it needs to go from local temps to say 14000ft temps, maybe higher, so additives are very different. MoGas may have a higher vaopour pressure, but it might not also.
Polarity: You are talking nonsense.
Static Charge: irrelevant for avgas v mogas. Aviation Kerosene is a different story.
The key here is that AVgas in Australia is the same as the US, or the UK, or anywhere else in the world. MoGas blends are local and also vary with each distributor. I.e. Local BP and Caltex service stations might source their fuel from the one distiller, but the distiller will blend the fuel based on the customer.
