I've always been fine with the idea of Wheelvan, since tbh in the very first G1 Episode, his alt mode looks more van-ish then car. Then there was CR/RID Wildride/X-Brawn in their super mode that looks very wheeljack as well. And here, we have him being a repair van. That is very much Wheeljack. My only issue is the head. And I'll be honest if it wasn't for the Cybertron scene in BB, I would have less of an issue. Becuase I could see this being a "young" version of Que/Wheeljack. But BB gave us a very G1-y design, and it feels weird going from that to this. As I've mentioned, Arcee looks like that Arcee, but with a earth mode now.
All that aside, I've seen some interesting rumor mongering about Nightbird maybe being Black Archnia, becuase the colors and naming scheme (Dark color/Animal); combined with certain elements of the toy, like the head looking kinda like the toy head, the very specific 8 headlights in place of 8 spider eyes. and a few other things. And her being a villian could also tie into how BA was a Predacon at first.
