Bucky red room theory

i was just watching Agent Carter and Dottie Underwood reminded me of a scene in Civil war when Bucky and Cap were talking about a girl named Dorothy, that Bucky called Dot. Is there any evidence that the girl and Dottie Underwood are the same person? It kinda shows connections as it was said that Bucky trained Widows in the red room and Dottie is a Widow, so maybe she was working with Hydra and scoped out Bucky before the he was shipped out, so thats why they chose him to experiment on in the beginning before Cap reduced them. Then she found out he fell of the train and that whole situation and she became involved as she had intel. I've also seen some theories about how after Dottie vanishes she becomes a red room trainer, so maybe they worked together then?


Anyway what do you guys think about this theory? or maybe I'm just being stupid and this is already a thing, or there are too many inconsistencies.
