Dakotaraptor is unlikely to turn up in my Mesozoic Menagerie, simply because it's too similar to Utahraptor, which has already crept in alongside Deinonychus and Velociraptor...
As to the (unproven) feather arrangement, that's basically a no-go area. I've been attempting two feathered Dinosaurs already, Archaeopteryx and a generic Oviraptorid. The Oviraptor is just going to stay bald - ugly sod anyway - but Archaeopteryx kind've has to have feathers since the impressions of them are hammered into the holotype fossil in Ultimate Blatantvision (which is what led many to speculate that it was actually a bird of some sort despite having the exact skeleton of a small theropod Dinosaur - at the time, science essentially worked on the lines of "if it has feathers, it's a bird" regardless of how completely, utterly and self-evidently saurian it is).
Convincing feathers are difficult in NWN, much like long, shaggy fur, only worse. They can be done through a combination of creative texturing and A LOT of extra weight in the poly count for the bigger wing and tail feathers added individually and layered up, but it's slow and frustrating. I mean, just look at the BioWare Angel wings. They're perfectly OK, but they don't really look convincingly feathery.
Mind you, in terms of polycount, the Archaeopteryx feathers probably aren't actually much worse than all the millions of spikes and scutes that I've been nailing on the Rajasaurus and Carnotaurus, so...
