That would be fairly dumb.
Optus Stadium has a completely different pitch to the old Waca. It isn't the lethal speed track of old (still quick, but it isn't the be all and end all). Plus, if the Gabba has a green tinge, it swings there. Adelaide isn't noted for steepling bounce, SCG spins but gives bowlers of all types a bit of help, and the MCG is basically a sporting wicket.
BTW - interesting that the Ashes will actually start in Perth rather than Brisbane. With Convict CCs record at the Gabba against England, I am a little surprised about that. Also means I will need to plan for a different week to watch the Gabba test which I was expecting first up.
Picking a load of 6'7" bowlers would be short sighted to say the least.
