It's a good idea, though it'll imply prying it from Octavia, someone who clearly doesn't want to part with it and actually enjoys the stuff the armor did to her, and even if we were to force her to hand it over, we're talking about a 7 feet tall mountain of muscle, rage and sadism. I don't think it could end well for our poor pc (or our anus)
Don't get me wrong, i'm all here for cursed relics, and a cursed armor that turns you into a goddamn juggernaut is cool as fuck, but the way Tav is presented and caracterized, i see it more likely a new legendary item with similar properties to her armor is added rather than her deciding to randomly giving it to us
