Combining Azorius, Dimir, Simic and Izzet. Except this doesn't work either because overload can't be used when an enciphered spell is copied, and there's no real reason for the "creature without a +1/+1 counter" when wizards have tried to keep overload all-upside.
For those confused why it wouldn't work (i.e. me), Overload is an alternate cost, as is "casting without paying mana cost", so 117.9a comes into play.
"117.9a Only one alternative cost can be applied to any one spell as it’s being cast. The controller of the spell announces his or her intentions to pay that cost as described in rule 601.2b."

Ah, sorry, thank you for finding the explanation!
