Una NPC for hideout?

I love what have you done with this NPC in terms of her having all this songs that you can ask her to sing, that's why i think it's such a waste to have her confined to Act1, i would love to have her on my hideout giving it a more pleasant vibe every time i come back from a expedition.

In fact i would love to get to unlock all the NPCs from all the acts and have them on my hideout, i grew affectionate to some of them and now they basically confined to campaign game-mode, having Una without Finn would be sad :(.
