G'day Gents,
Sorry to chime in late here but I just came across this post and I thought I would share some insights about a couple of things you should know before thinking about or trying to possibly upgrade the Ozzie PHEVs to ChaDeMo. I seriously looked into this issue some time back but was stopped in my tracks when I found that the Battery Packs are actually slightly different (i.e. Pack A and Pack B). We have Pack A here in OZ but the Japanese / European fast charge ChaDeMo implementation requires a Pack B.
I posted some technical documents some time ago on the forum and one of them was the Technical Highlights Manual. On page 112, not least, it states that a 'Quick Charge Fuse' and 'Quick Charge Contactor' is not fitted to the OZ battery pack model. Here's the link to the document (page 112 refers).

In addition, there appears to be other considerations also, such as the cooling system, which is actively employed to not only cool the battery, but the onboard charger also (page 120 refers). Without reading the document in detail here, I am unsure what implications for cooling may also have to be taken into account.
I hope this helps ...
Cheers
Peter
