Would it be possible to have the Blood of Pharaohs, Roman demigod legacy, Greek demigod legacy and being a Norse demigod or would you just end up like Frank and have something that is contradicting all of those powers?

There's nothing in any of the series that suggests it's impossible, but such an individual would be incredibly overpowered; a bit too much if you ask me. We've seen that Frank, a Roman demigod with divine Greek ancestry, had his life-force tied to a piece of wood to balance out his immense powers. I'm guessing that a person with the mix of all three pantheons would have something similar.
Anyway, I'm sure that the gods have measures in place to prevent this sort of thing from happening. They were able to keep Camp Half-Blood and Camp Jupiter apart for centuries, and besides, including a character with direct ties to all pantheons is a bit tacky for my tastes. The crossovers are enough.
