Hera is One

Guys, I'm stuck on the Roman God side in Percy Jackson.

I chose Juno (Hera) as the main FMC, but now I have a problem.

In this world, Jupiter and Zeus are the same, so there's no separate ruler for the Roman side.

Now I don't know what to do. How can I mix them? Who should rule the Roman gods?

Any ideas?

and saturday and sunday is my off as you guys know!
