Hm... what lead you to the conclusion that the Maiden is basically a nu-Yozi? She's much nicer than their like!
Eeeh, as
a stalwart Infernal player an ordinary Solar citizen, I disagree. I mean, I also don't see where the nu-Yozi thing came from, but I don't think the Maiden's motivations are any better than those of a particularly benign Yozi or a pre-Yozification Primordial.
Like, if you randomly plopped She Who Lives In Her Name into the Human Sphere, her immediate reaction would probably be confusion followed by a brief existential crisis, and then anything from attempting to insert herself into whatever she perceives as the 'righteous hierarchy,' of this new, strange cosmos, or maybe just fucking off into deep space to pursue the Shining Answer. Some of the Yozis would probably run around fucking shit up or trying to conquer stuff (Malfeas, Adorjan, Ebon Dragon, Isidoros,) others wouldn't do anything much at all (Qaf, Sacheverell, Oramus, Cecelyne, maybe Szoreny,) and others would be somewhere in between (Hegra, Metagaos, Kimbery.)
It's a pretty wide palette of creatures, I think we'd have to specify which category of Yozi we're talkin' about.
(Edit: Actually, Isidoros is probably also in that last category - he'd probably be rather pretty content running around the Voyaging Realm charging into mountains and breaking people's toys.)
