Datamined stuff are her inventory, so it is quite likely that she will be at least a temporary companion.
But I agree that the chances that she will be a real companion are not that great.
But man cen, dream, man can dream...
P.S.
I don't think Khalit was exactly the best husband.
And her short mourning time probably has something to do with her being a druid.
Death is part of the cycle of nature... or something similar.
Or it was completely the other way around.
Maybe his death broke her completely (though she didn't show it) and so she clung to another man so she wouldn't feel so alone.
And Charname was just an asshole because he abused her vulnerability and pushed her further.
