Another thing to consider is that we have a direct pact with the current iteration of Titania. Perhaps there might be a way for them to allow us to temporarily call on a demi-proxy of Titania to aid our fights later down the road? After all, Feo Ul can do something similar already by providing us contact with our retainers while we're on the first, so I don't think it's too much of a stretch. Although gameplay-wise, I'm not sure how Demi-Titania would fit in along with Bahamut and Phoenix, but that's a separate discussion for a different thread I think.
