Hi Amir,
If I'm not wrong, this topic has already been discussed... Oracle says that they will not support your configuration after the third day because they don't want to run into many customers doing indefinitely long rolling upgrades. Technically there are no reasons, I think it's more a political one.
Anyway, I would do the opposite: ask the list and validate from Oracle... just my 2 cents
