Can a 153 Bishop solo Ravana?

I'm not sure if you can even pick which Ravana to fight against, but I'm able to solo Capt. Latanica in just a few minutes with AR/Bahamut, and he has 2 million HP.
Could it be done?

Unless you need 2 people to go in <_< do you? No one seems to actually be doing Ravana yet, maybe it's since Bishops get the suns so damn fast. Got 6 while my girlfriend has 2. D:

I would assume you could solo it, seems like there's nothing stopping you aside from entrance requirements. I do think theres a minimum number to enter but if the others d/c theres nothing stopping you from soloing...
