They could always go the route that the 'Gods' are in fact shapeshifters or powerful practioners of magic so were worshipped as God. Thus they aren't opponents that Regina/Emma/Rumple could not dispatch despite it being a challenge.

Although I've always been against introducing Greek Mythology, the immortality could be explained by magic. The togas would obviously be done away with but I could see Hades (whose fearsome powers have long faded being interested in TDO's dagger (providing nothing happens to it in 3b) Emma venturing into the Underworld, and even seeing Neal there? (Haha, just desperate to ensure there will be more MRJ appearances)

Hercules? Why not!

Like I said, I'm not 100% but with the right treatment, it could happen and I dare say I think I would enjoy it!
