I was think for Camarasaur at first, but then saw those really short hindlimbs and the Euhelopus-like head. Your speculative/fictious dinosaurs are a challenge and real fun for one to guess their affinities.
Still, I'm going to say that its possible they had feathers, just not highly likely they would look like this :/. What really irks me though about it, is the coat of feathers. I mean, the "elephant style" of sparse feathering is more natural and realistic, yet I've only seen over-done fuzzball or musk ox Sauropods when feathers are added. I don't understand why this is .
I can't help but thinking, if it is some kind of euhelopodid?
But yeah, this looks really good to me. And the idea isn't impossible.
