Get a dex bonus from bloodrage?

[Genuine]

What it says on the tin. I know that the Urban Barbarian can take his rage bonus to Dex (instead of Str + Con), is there any way for a bloodrager to do this?

I know none of the archetypes open it up, is there a feat or something that I've missed that could accomplish the same?

Nope, doesn't exist yet. I wouldn't be surprised if an Urban Bloodrager pops up at some point, though.
